If we label the sides of the triangle a, b and c, and assume c is the hypotenuse, the "formula" for the theorem is c^{2} = a^{2} + b^{2}. If you want to find a or b, simply isolate that variable in the formula before substituting the numbers:
If you plug in the values for the hypotenuse and the known side, you can then find the unknown side. Hope this helps, Leeanne
