XY is parallel to QU, b = 4x, e = x + 2y, and d = 3y + 8
Now, we know that b and d are supplementary pairs so b+d = 180
4x + 3y + 8 = 180
4x + 3y = 172 : Eq 1
Also e=d (alternate interior angles)
x + 2y = 3y + 8
x - y = 8 : Eq 2
Solving both equations, we get
x = 28 and y = 20
Now, h=e (vertically opposite angles) = x + 2y = 28 + 40 = 68
Answer - D
