Practice using the Pythagorean theorem to solve for missing side lengths on right triangles.  Each question is slightly more challenging than the previous. Created by Lindsay Spears.

## Pythagorean theorem

The equation for the Pythagorean theorem is
$a^2 + b^2 = c^2$
where $a$ and $b$ are the lengths of the two legs of the triangle, and $c$ is the length of the hypotenuse.
The hypotenuse is the longest side and is across from the right angle. The two legs are the shorter sides that form the right angle:
Find the value of $x$ in the triangle shown below.
