    use the pythagorean theorem : x^2 = 24^2 - 12^2 solve for x

    Pythagorean Theorem: a^2 + b^2 = c^2 In this case, you have the hypotenuse and the height so you can fill in it as: 12^2 + b^2 = 24^2 *b is the same thing as x and you can just solve for the missing variable by squaring the numbers and moving 12^2 over to the right side by subtracting it. Voila! the answer!

    @swin2013 So 24^2=576, 12^2=144, 576-144=432 but whats the square root?
