The first thing you need to do is be a little more precise in your language. This problem only works if your triangle is a right triangle. The long side of a right triangle is a hypotenuse, not a "hypotinuse".

Let represent the measure of the short leg. Then must represent the measure of the longer leg and must represent the measure of the hypotenuse.

The square on the hypotenuse is equal to the sum of the squares on the other two sides, so:
