Answer:
YX = 22
Step-by-step explanation:
Similar triangles. So,

Cross multiplication
45*(x+8) = 30 * (3x - 9)
45x + 360 = 90x - 270
360 = 90x - 270 - 45x
360 = 45x - 270
360 + 270 = 45x
45x = 630
x = 630/45
x = 14
YX = x +8 = 14 + 8 = 22
Drawing out the triangle, we get the one below. We can use the trigonometric ratio of
tan to solve this problem.

x=21.5:)
