Four intersecting lines, t, v, u, and w, are shown in the diagram.

 x = 12

Explanation:

Line w and line t are parallel if and only if the corresponding angles (4x+60) and (9x) are congruent.

9x = 4x+60

9x-4x = 60

5x = 60

x = 60/5

x = 12

If x = 12, then

9x = 9*12 = 108

4x+60 = 4*12+60 = 48+60 = 108

Both corresponding angles would be 108 degrees if x = 12. So this confirms we have the right x value.
