Answer:


4√(2)

Explanation:

So first, you find the height of the triangle, so you can use the Pythagorean Theorem:


3^2 + h^2 = 5^2\\9 + h^2 = 25\\h^2 = 16\\h = 4

So the height is 4.

Then, since the right triangle is a 45 - 45 - 90 triangle, you have the ratio of the sides is a:a:
√(2) a

Since you have the value of a = 4, the value of x, is a
* √(2) =
4√(2)
