2) Alternate exterior, so 16x + 22 = 134
4) (9x + 2) is supplementary to an alternate interior angle, so (9x + 2) + 133 = 180
6) Corresponding angles, so 6x - 2 = 11x - 47
7) Alternate interior, so 5x + 75 = 13x - 21
8) Each angle is supplementary to a corresponding angle, so (5x+3) + (9x - 33) = 180
Now just solve for x.
