Due to the corresponding angle property, which requires that the sum of neighboring opposite angles be 180, the angles are 90 and 79.8.
what is angle ?In Euclidean geometry, an angle is a shape that is made up of two rays, known as the angle's sides, that meet at a point in the middle known as the angle's vertex. Two rays may combine to form an angle in the plane where they are positioned. When two planes collide, an angle is also created. They are referred to as dihedral angles. An angle in plane geometry is the possible configuration of two rays or lines that share a termination. The origin of the English term "angle" is the Latin word "angulus," which meaning "horn." The vertex is the point where the two rays, also known as the sides of the angle, converge.

A soft drink is available in two packs - (i) a tin can with a rectangular base of length 5 cm and width 4 cm, having a height of 15 cm and (ii) a plastic cylinder with circular base of diameter 7 cm and height 10 cm. Which container has greater capacity and by how much?
Answer: To find the capacity of the tin can, we can use the formula for the volume of a rectangular prism, which is length x width x height. In this case, the length is 5 cm, the width is 4 cm, and the height is 15 cm. So the volume of the tin can is 5 x 4 x 15 = 300 cubic cm.
To find the capacity of the plastic cylinder, we can use the formula for the volume of a cylinder, which is pi x radius squared x height. The diameter of the circular base is 7 cm, so the radius is half of that, or 3.5 cm. So the volume of the plastic cylinder is pi x (3.5 cm)^2 x 10 cm = 385.4 cubic cm.
So the plastic cylinder has a greater capacity by 385.4 - 300 = 85.4 cubic cm.

Rectangle is similar to rectangle . Which proportion can be used to find the value of x?
If rectangle is similarity to rectangle, to find the value of x we use proportion (c) 5/12 = 2/x.
What is called similarity of shapes?When applying a scale factor, similar shapes are enlarged versions of one another.
All of the matching angles and lengths in related shapes are equal and in the same ratio.
If two figures share the same shape, congruent corresponding angles (which means the angles in the same places of each shape are the same), and identical scale factors, they are said to be "similar figures."
Given that rectangle EFGH is similar to rectangle JKLM, it means the corresponding sides of both rectangles are similar, and as such the ratios if the corresponding sides of rectangle EFGH and rectangle JKLM would be equal.
Thus, EF/JK = FG/KL
Since, EF = 5; JK = 12; FG = 2; and KL= x, therefore, the proportion to use in finding x would be:
5/12= 2/x

the premiter of a rectangle is the some of the lengths and its four sides which expression where1=length and w = width does not show this relationship
Answer: The perimeter of a rectangle is the sum of the lengths of its four sides which is given by the expression: P = 2l + 2w (where l is the length and w is the width)
The expression that does not show this relationship is P = l + w
It doesn't show the relationship because it doesn't take into account the two sides that are equal to the width and the two sides that are equal to the length.
P = 2l + 2w shows the relationship as it considers both length and width of the rectangle twice, once for each pair of sides.

5. The third term in an arithmetic sequence is 10 and the fifth term is 26. If the first term is a₁, which is an
equation for the nth term of this sequence?
1) a = 8m+10
2) a = 8n - 14
3) a = 16n+10
4) a, = 16n-38
The equation for the nth term of this sequence is [tex]a_{n}[/tex] = 8n - 14. The solution has been obtained by using the concept of arithmetic progression.
What is arithmetic progression?
The difference between any two consecutive integers in an arithmetic progression (AP) sequence of numbers is always the same amount. It also goes by the name Arithmetic Sequence.
We are given that the third term is 10.
This means that [tex]a_{3} =10[/tex]
So, n=3
Substituting this value in the given equations, we get
1) [tex]a_{n}[/tex] = 8*3+10 = 34
2) [tex]a_{n}[/tex] = 8*3 - 14 = 10
3) [tex]a_{n}[/tex] = 16*3+10 = 58
4) [tex]a_{n}[/tex] = 16*3 - 38 = 10
So, the second and the fourth equation satisfy the condition.
We are also given that the fifth term is 26.
This means that [tex]a_{5} =26[/tex]
So, n=5
Substituting this value in the given equations, we get
2) [tex]a_{n}[/tex] = 8*5-14 = 26
4) [tex]a_{n}[/tex] = 16*5 - 38 = 42
So, the second equation satisfies the condition.
Hence,the equation for the nth term of this sequence is [tex]a_{n}[/tex] = 8n - 14.

Rider complete 160 lap the race to complete the race. With each lap meauring 0. 25km. If a ride ha already cylcled 4. 75km how many lap doe he have left to finih the race
The rider has 141 laps left to finish the race.
If a rider has already cycled 4.75 km, and each lap measures 0.25 km, we can determine how many laps the rider has completed by dividing the distance already cycled by the distance per lap.
To find out how many laps the rider has left to finish the race, we will use the information on the total number of laps to complete the race: 160 laps.
The rider has completed:
4.75 km / 0.25 km = 19 laps
The rider has yet to finish:
160 laps - 19 laps = 141 laps
So the rider has 141 laps left to finish the race.
Therefore, the rider has 141 laps left to finish the race.

A phone case is 10 times cheaper than the phone. Herman paid 660 for his phone and case. What was the cost of the phone and what was the cost of the phone case
Answer:
Let x be the cost of the phone.
we know that the cost of the phone case is 10 times cheaper than the phone so the cost of the case is x/10
We also know that the total cost of the phone and the case is 660.
so we can write an equation:
x + (x/10) = 660
We can solve this equation for x by multiplying both sides by 10:
10x + x = 6600
11x = 6600
x = 600
So the cost of the phone is 600 and the cost of the phone case is 600/10 = 60

The system of equations that represents this situation is D + Q =24 and 10D + 25Q = 465 with 15 and 9 quarters and dimes respectively.
What are dimes?The dime is a ten-cent coin that is one-tenth of a dollar and is officially known as "one dime" in American use. The Coinage Act of 1792 initially allowed this denomination.The dime is the smallest and thinnest denomination now in circulation in the United States.Its obverse has President Franklin D. Roosevelt's profile, while its reverse features, from left to right, an olive branch, a torch, and an oak branch.The dime is the only currency in general circulation in the United States that is not valued in terms of dollars or cents. The cost to make a dime in 2011 was 5.65 cents.Given that
let the quarter be represented by Q and dimes with D
D + Q =24 (multiply this by 10)
10D + 10Q = 240
10D + 25Q = 465
Subtracting both the equations:

What is linear inequality?
A linear inequality is a mathematical statement that describes a relationship between two or more variables that form a half-plane when graphed. The equation of a linear inequality is in the form of "ax + by < c" or "ax + by > c" or "ax + by <= c" or "ax + by >= c", where x and y are variables, and a, b and c are constants.
An inequality that could be used to determine the minimum number of gallons, g, of gasoline Darla would need to drive 120 miles to her brother's house is:
g >= 120/37.5
This inequality states that the number of gallons, g, must be greater than or equal to the number of miles Darla needs to drive, 120, divided by the number of miles per gallon her car gets, 37.5. This is because Darla wants to ensure that she has enough gasoline to make the trip, and she may not want to risk running out of gas on the way.
Another way to write this inequality is
g * 37.5 >= 120
This inequality represents the same meaning as before, we multiply g by the number of miles per gallon the car gets, 37.5 and it should be greater than or equal to the distance she needs to travel which is 120 miles.
Hence, the inequality can be written as g * 37.5 >= 120.

(x−1)(x^3+3x^2−10x−24)=(x−1)(x+2)(x^2+x−12)
Solve the quadratic equation x^2+x−12=0.
x^2+x−12=0
x^2+4x-3x-12=0
x(x+4)-3(x+4)=0
(x+4)(x-3)=0
So, (x−1)(x+2)(x^2+x−12)=(x−1)(x+2)(x−3)(x+4)
Therefore, x^4+2x^3−13x^2−14x+24=(x−3)(x−1)(x+2)(x+4) .
The Rational Root Theorem tells us that if the polynomial has a rational zero then it must be a fraction q/p, where p is a factor of the constant term and q is a factor of the leading coefficient.
We can see that p(1)=0 so x=1 is a root of a polynomial h(x).
Divide the polynomial by (x-1) -
(x^4+2x^3−13x^2−14x+24)/(x-1)=(x^3+3x^2−10x−24)
Divide (x^3+3x^2−10x−24) by (x-3) -
(x^3+3x^2−10x−24)/(x-3) = (x^2+6x+8)
To find the last zero, solve equation x+4=0
x=-4
Therefore, the real roots are - x = 1, 3, -2, -4.

An investor invested a total of $1,600 in two mutual funds. One fund earned a 9% profit while the other earned a 4% profit. If the investor's total profit was $84, how much was invested in each mutual fund?
The amount invested in each mutual fund is $400 and $1200 respectively
What is Simultaneous equation?Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time. For example, below are some simultaneous equations: 2x + 4y = 10 and 8x − 4y = 2
Let represent the amount the first fund get by x and the amount the second fund get by y.
Therefore x+y = 1600 equation 1
and 9/100 × x + 4/100 × y = 84
9x/100 + 4x/100 = 84
multiply through by 100
9x + 4x = 8400 equation 2
using elimination method
9x+ 9y = 14400 equation 3
9x + 4y = 8400 equation 4
subtract equation 4 from 3
5y = 6000
divide both sides by 5
y = 6000/5
y = $1200
substitute 1200 for y in equation 1
1200+x = 1600
x = 1600-1200
x = 400
Therefore the first fund will get $400 and the second fund will get $1200
