Answer: x = 120

Step-by-step explanation:

Okay so you have three similar right triangles. To find x, you can set up an proportion $\frac{shorter leg}{long leg} = \frac{64}{x} = \frac{x}{225}$ since similar figures are in proportion. By cross multiplying and finding the square root of x^2, you result in x equaling 120.
