1. To solve this exercise you must apply the Pythagorean Theorem, which is:
Where 
is the hypotenuse, and 
and 
are the other sides of the triangle.
2. You have that the sides given measures 12 inches. 1 feet has 12 inches. Therefore, this side measures 1 feet.
2. Then, when you solve for one of the sides and substitute the values given in the problem into the formula shown above, you obtain that the length of the side of the rigth triangle is:
