That is your triangle.
Now, since its a right triangle, we can use the Pythagorean theorem to solve for x.
The equation for the Pythagorean theorem is this: 
So we plug in the values.

We solve for x.

Get everything to the left side of the equation. (x^2 + x^2 = 2x^2, - x^2 = x^2;
-18x - 18x = -36x; 81 - 81 = 0)

Add 36x to both sides, then divide by x.

<u>Longest Leg = 36</u>
<u>Hypotenuse = 45</u>
