Answer 1

Answer:

$4\sqrt{2}$

Step-by-step 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:$\sqrt{2} a$

Since you have the value of a = 4, the value of x, is a $* \sqrt{2}$ = $4\sqrt{2}$
