Answer:   x = 100

=========================================================

Explanation:

The triangles are similar. We can prove this through the angle angle similarity postulate.

This means we can set up the proportion below to solve for x

(short horizontal)/(long horizontal) = (short vertical)/(long vertical)

12/150 = 8/x

12x = 150*8 .... cross multiply

12x = 1200

x = 1200/12 ... divide both sides by 12

x = 100

------------------

As confirmation:

12/150 = 0.08

8/100 = 0.08

This shows that 12/150 = 8/100
