I need to know how to find the measure of angle a.
Answer:
90°
Step-by-step explanation:
We need expressions for the measures of the three interior angles. Then we add them and set the sum equal to 180. Then we solve for x. Finally, we use the value of x in x + 100 to find the measure of angle A.
Let's first find an expression for each angle.
Angle A: m<A = x + 100
Bottom left angle: The interior angle is vertical to the angle measuring x + 60, so the interior angle also measures x + 60.
Bottom right angle: Let's call the measure of the interior angle y. y and the angle measuring 140° are supplementary, so y + 140 = 180; y = 40.
Now that we have expressions for the three interior angle measures, we add them and set the equal to 180.
(x + 100) + (x + 60) + 40 = 180
x + 100 + x + 60 + 40 = 180
2x + 200 = 180
2x = -20
x = -10
The measure of angle A is x + 100, and x = -10
m<A = x + 100 = -10 + 100 = 90
Answer: 90°

Use the figure below to solve for the value of x.
Given:
A figure of a right triangle and an altitude form the right angle vertex to hypotenuse.
To find:
The value of x.
Solution:
From the given figure, it is clear that the altitude divides the hypotenuse in two segments x and 8.
Length of altitude = 18
If an altitude divide the hypotenuse in 2 segments, then according to the geometric mean theorem, the length of the altitude is the geometric mean of two segments of hypotenuse.
By using geometric mean theorem, we get
[tex]18=\sqrt{x\times 8}[/tex] [tex][\because \text{Geometric mean of }a,b,c:b=\sqrt{ac}][/tex]
[tex]18^2=8x[/tex]
[tex]324=8x[/tex]
Divide both sides by 8.
[tex]\dfrac{324}{8}=x[/tex]
[tex]40.5=x[/tex]
Therefore, the value of x is 40.5.
Which of the following equations best verifies the reasonableness of the solution for

The equations best verifies the reasonableness of the solution will be log₃ 2187 = 7 and log₃ (3⁷) = 7. Then the correct options are A and E.
What is a logarithm?Exponents can also be written as logarithms. A number base logarithm is similar to some other number. It is the exact inverse of the exponent expression.
The equation is given below.
log₃ x = 7
Take anti-log on both side, then we have
x = 3⁷
x = 2187
Then the equation is satisfied by 2187. Then we have

Mariel deposited ₱6,500.00 in an account that offers 5% interest compounded semi-annually. How much money is in his account at the end of five years?
Answer:
The amount is 8,322
Step-by-step explanation:
To get this , we are going to use the compound interest formula
A = P( 1 + r/n)^nt
A is the amount we are calculating
P is the amount deposited = 6,500
r is the interest rate = 5% = 5/100 = 0.05
n is the number of times per year the interest is compounded
= 2 since it is semi-annually
t is the number of years = 5
Substituting these values, we have it that ;
A = 6,500(1 + 0.05/2)^10
A = 6,500(1.025)^10
A = 8,322

Answer:
15x+8=180-97 , solve for x and u shall get the answer
Answer:5
Step-by-step explanation:
Since 97 and the other angle together make a straight line, you can find the angle by doing 180-97 which is 83. Then you 15x+8=83. 15x=75. x=5.

Answer:
3x² * (6x² + 4x - 8) = 18x⁴ + 12x³ - 24x²
2x * (9x³ + 6x² - 12x) = 18x⁴ + 12x³ - 24x²
x² * (18x² + 12x - 24) = 18x⁴ + 12x³ - 24x²
6x² * (3x² + 2x - 4) = 18x⁴ + 12x³ - 24x²
Step-by-step explanatation:
Let's set unknown variables as y (and y₁, y₂, etc)
Question 1:
y * (6x² + 4x - 8) = 18x⁴ + 12x³ - 24x²
So, divide both sides by (6x² + 4x - 8)
y = 3x²
Question 2:
2x * (9x^y₁ + y₂*x^y₃ - y₄*x) = 18x⁴ + 12x³ - 24x² '
Divide both sides by 2x.
(9x^y₁ + y₂*x^y₃ - y₄*x) = 9x³ + 6x² -12x
y₁ = 3, y₂ = 6, y₃ = 2, y₄ = 12
Question 3:
x^y * (18x² + 12x - 24) = 18x⁴ + 12x³ - 24x²
Divide both sides by (18x² + 12x - 24)
x^y = x²
Question 4:
y₁ * x^y₂ * (3x² + 2x - 4) = 18x⁴ + 12x³ - 24x²
Divide both sides by (3x² + 2x - 4)
y₁ * x^y₂ = 6x²
y₁ = 6, y₂ = 2

What is mean by Subtraction?
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
If you spent 58 minutes doing English homework and 47 minutes doing math homework.
Now,
Since, The time for doing English homework = 58 minutes
And, The time for doing Math homework = 47 minutes
So, The time more to spend doing English homework = 58 - 47
= 11 minutes
Thus, There are 11 minutes more time to spend doing English homework.
