**MathGuru**, Monday, May 7, 2012 at 11:23amUse the following:

a^2 + b^2 = c^2

a^2 + 5^2 = 13^2

a^2 + 25 = 169

Subtract 25 from both sides (whatever operation you do to one side of an equation you must do to the other side as well):

a^2 = 144

Take the square root of both sides:

a = 12

Hope this helps.
