Answer 2

Angle 2 and angle 7 are congruent....they equal each other. So set them equal to each other and solve for x.

5x + 40 = 11x - 20 -- subtract 40 from both sides
5x = 11x - 20 - 40 -- subtract 11x from both sides
5x - 11x = -20 - 40 -- combine like terms
-6x = - 60 -- divide by -6
x = 10

you got it correct :)
