Answer: B. x = 6</h3>
==========================================================
Explanation:
Since the vertical lines are parallel, this means the alternate exterior angles shown are congruent.
Set them equal to each other and solve for x.
15(x+2) = 120
15x+30 = 120
15x = 120-30
15x = 90
x = 90/15
x = 6
Or we could have the steps like this
15(x+2) = 120
x+2 = 120/15
x+2 = 8
x = 8-2
x = 6
