    I know how to use the Pythagorean Theorem (A^2 + B^2 = C^2), but I don't know how to get a leg's distance based off of the hypotenuse and another leg.

    Well, what's 13^2? And what's 12^2? And what's the difference between them?

    If the hypotenuse^2 = side1^2 + side2^2, then side2^2 would be hypotenuse^2 - side1^2

    13^2 = 169 12^2 = 144 Would the answer be 25?

    I know that isn't in the options. That's what I got.

    Close... 25 is the answer squared. What we're after is the square root of 25, and THAT will be your answer! :-)

    Square root of 25 is 5. Heheh.
