Answer:
The answer is 28. I will explain below.
Step-by-step explanation:
Take a look at the angles, and determine what relationship they might be in. In this case, they are a pair of vertical angles. Recall that vertical angles are congruent, meaning the same measure. So set 3x+2 equal to 86, the equation looking like this: 3x+2=86. Now subtract the 2 from 86 to get 84, and you now have 3x=84. Divide 3x by three, and 84 by three. You should end up with x=28, and that's your answer.
