Answer: x=11
Step-by-step 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
