Question

What’s the value of x?

Answer 1

Answer:

x=28

Step-by-step explanation:

3x+2 is equal to 86 degrees

So the setup of the equation would be 3x+2=86

3x+2=86

   -2  -2

3x=84

$\frac{3x}{3}$ $\frac{84}{3}$

x=28

Answer 2

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.
