Question

The measure of two angles are (4x+25) and (8x-30). What is the value of x, if these angles are congruent?

A. x = 5
B. x = 10
C. x = 15
D. x = 20

Answer 1

To find the value of x, set the two angles equal to each other and solve for x. None of the options provided matches the value of x in the equation. x = 13.75

Step-by-step explanation:

To determine the value of x, we need to set the two angles equal to each other and solve for x.

(4x+25) = (8x-30)

Combine like terms and isolate x:

4x - 8x = -30 - 25

-4x = -55

Divide both sides by -4:

x = 13.75

None of the options provided matches the value of x in the equation.
