Question

A and B are vertical angles. If m A = (3x+3)° and m B= (4x-8)°, then find the value of x.

Answer 1

Answer: x=11

Explanation:

First, since angle A and angle B are vertical angles, that means that they are congruent. If they are congruent, then the m of angle A equals the measure of angle B. So, (3x+3)=(4x-8). Simplify using algebra so that in the end, you will find that x=11.

3x+3=4x-8

3=x-8

11=x
