a triangle has two angles that measure 18.6 degrees and 113.4 degrees respectively. what is the measure of the third angle?
Sum of all angles of a triangle = 180°
Let the third angle be x.
So, 18.6° + 113.4° + x = 180°
=> 132° + x = 180°
=> x = 180° - 132°
=> x = 48°
So, the third angle is 48°.
Step-by-step explanation:
sum of all Δangle of a triangle = 180°so, let 3rd angle be x18.6° + 113.4° + x = 180°132° + x = 180°x = 180° - 132°x = 48°MARK ME AS BRAINLIST
A wire attached to the top of a building makes a 15° angle with the ground. If the building is 25 feet high, how
long is the wire?
Answer:
96.6feet
Step-by-step explanation:
,
From the attachment, we can see that a triangle is formed.
From trigonometry,
Sin(X)= opposite/hypothesis
Where Opposite sides=25feet
Hypotenuse sides= X feet
Sin(15)= 25/X
Cross multiply
Sin(15)= 0.2588
0.2588=25/X
X= 25/0.2588
X=96.6feet
Hence, the wire is 96.6 feet high

Let's set Huilan's age to h and Thomas's age to t.
Since Huilan is 13 years younger than Thomas, we can write:
h = t - 13The sum of both their ages is 41, so let's combine the variables h and t together.
h + t = 41We said that h = t - 13, so substitute this value into the equation.
(t - 13) + t = 41Combine like terms.
2t - 13 = 41Add 13 to both sides of the equation.
2t = 54Divide both sides of the equation by 2.
t = 27Thomas's age is 27 years old.

The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal costs $78.25 before the discount, and they leave a 20% tip. If the tip applies to the cost of the meal before the discount, what is the total cost of the meal? Round your intermediate calculations and answer to the nearest cent.
Assumed 20% tip is on the discounted meal.
The cost of the meal is $78.65 .
The cost of the meal after discount (15%) is
78.65⋅(1−0.15)≈$66.85
Tip (20%) is : 66.85⋅0.2≈$13.37
Total cost of the meal is 66.85+13.37≈$8

Complete the equation of the line whose slope is −2 y-intercept is (0,3)
Answer:
y=-2x+3
Step-by-step explanation:
hope this helps
Answer:
y = -2x + 3
Step-by-step explanation:
So you want to put it in the form y = mx + b where m is the slope and b is the y-intercept (an example of an equation in this form is y = 2x + 1).
It tells you that the slope is -2 and the y-intercept is at y = 3, so the equation would be:
y = -2x + 3

What is the equation of the line that passes through (0, -2) and has a slope of 0?
y = -2
y = 2
x = 2
Answer:
y = - 2
Step-by-step explanation:
A line with a slope of 0 is a horizontal line parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (0, - 2) with y- coordinate - 2 , then
y = - 2 ← equation of line

triangle ABC is isosceles with AB=AC and angle A=50°. the bisector of angle B and angle C meet at D. find the measure of BDC
Answer:
115 degrees
Step-by-step explanation:
From what I'm visualizing, D is a point of another isosceles triangle within ABC, so to find the measure of angle BDC, we have to find the other angles first.
First, we have to find angle B and C. since this is an isosceles triangle and AB=AC, these two angles are equal and we find their angle measure by subtracting the known angle A, from the total measure of all angles in a triangle, 180
180 - 50 = 130
then divide that by two to get the two equal angles
130/2 - 65
angle bisector divides the angles in half so the measures of CBD and BCD are 65/2
that leaves the last remaining angle BDC. Again, we take the known angles and subtract them from 180
180 - 65/2 -65/2 = 115

A. 4
B. 4.5 < 718 < 5
C. 8.5 < V18 < 9.5
D. 17 < 118 < 19
Answer: C
Step-by-step explanation:
Option A is true comparisons among the given option as the number are in increasing order A. 4 < √18 < 4.5 .
To determine if this is true, let's calculate the square root of 18:
√18 ≈ 4.2426
Substituting the value into the comparison:
4 < 4.2426 < 4.5
This statement is true because 4 is indeed less than 4.2426, and 4.2426 is less than 4.5. Therefore, Option A is true.
B. 4.5 < √18 < 5
Option B states that 4.5 is less than the square root of 18, and the square root of 18 is less than 5. We have already determined the value of the square root of 18 as approximately 4.2426. Evaluating this comparison:
4.5 < √18 < 5
This statement is also true because 4.5 is not less than 4.2426, and 4.2426 is less than 5. Therefore, Option B is not true.
C. 8.5 < √18 < 9.5
Option C states that 8.5 is less than the square root of 18, and the square root of 18 is less than 9.5. We have already established the value of the square root of 18 as approximately 4.2426. Evaluating this comparison:
8.5 < √18 < 9.5
This statement is false because 8.5 is not less than 4.2426. Therefore, Option C is not true.
D. 17 < √18 < 19
Option D states that 17 is less than the square root of 18, and the square root of 18 is less than 19. Evaluating this comparison:
17 < √18 < 19
This statement is true because 17 is not less than 4.2426, and 4.2426 is less than 19. Therefore, Option D is not true.
In conclusion, among the given options, Option A is true comparisons:
A. 4 < √18 < 4.5

Find the area of the similar
figure.
20cm
25cm
Area = 320cm2 Area = [?]cm2
Given:
Base of smaller figure = 20 cm
Area of smaller figure = 320 cm²
Base of the larger figure = 25 cm
To find:
The area of the larger figure.
Solution:
We know that the areas of the similar figure are proportional to the square of corresponding sides of them.
Let A be the area of the larger figure.
[tex]\dfrac{\text{Area of the larger figure}}{\text{Area of the smaller figure}}=\dfrac{(\text{Base of the larger figure})^2}{(\text{Base of the smaller figure})^2}[/tex]
[tex]\dfrac{A}{320}=\dfrac{(25)^2}{(20)^2}[/tex]
[tex]\dfrac{A}{320}=\dfrac{625}{400}[/tex]
[tex]\dfrac{A}{320}=\dfrac{25}{16}[/tex]
Multiply both sides by 320.
[tex]A=\dfrac{25}{16}\times 320[/tex]
[tex]A=500[/tex]
Therefore, the area of the larger figure is 500 cm².

Murray’s father deposited $6,000 of his savings into two accounts. One account earns 1.5 percent interest, and the other account earns 2.5 percent interest. At the end the year, the interest in the account that earned 2.5 percent was $110.00 more than the other account. Which system represents the amounts of money, x and y, that was put into each account?
x + y = 6,000. 0.025 x + 0.015 y = 110.
x + y = 6,000. 0.25 x + 0.15 y = 110.
x + y = 6,000. 0.025 x minus 0.015 y = 110.
x + y = 6,000. 2.5 x minus 1.5 y = 110.

for question 6, write the equation in standard form ax by=c (show your work). from: y=m b to Ax By=c
Since you have the slope m = -3 and the point (-9, -2) you can use the Slope Intercept Form to find b
y = mx + b
-2 = -3(-9) + b
-2 = 27 + b
Subtract 27 from both sides of the equation to get b
-2 - 27 = b
-29 =b
And the Slope Intercept Form
y = -3x -29
Now you can rearrange the Slope Intercept Form to give the Standard Form by adding 3x to both sides of the equation.
y + 3x = -29
I hope you find this useful and if you have any questions please send me a message.

Step-by-step explanation:
We are given a polynomial and are asked to solve or factor it I am assuming.
To solve this, there is a certain rule I like to follow, which is for b (in this case 5), you have to find two numbers that multiply to it, and for c (in this case 13), you have to find two numbers that add to it.
Since no two numbers multiply to 5 and add to 13, therefore this polynomial is not factorable.
