Find the indicated side of the
right triangle.

Answer 1

Answer: 9

Explanation:

Answer 2

?=9

Explanation:

We have a special right triangle, the 45-45-90 triangle.

In a 45-45-90 triangle, the side lengths are x, and the hypotenuse is x√2.

Since we know that the side length is 9, this means that:

`x=9\\\text{Hypotenuse}=x\sqrt2\\\text{Hypotenuse}=9\sqrt2`

The ? is 9.
