Answer 1

`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)`
