    A^2 + b^2 = c^2

    3^2 + b^2 = 11^2

    9 + b^2 = 121

    b^2 = 121 - 9

    b^2 = 112 ...

    b = square root of 112

    b = 10.58

    Pythagorean theorem (or however it is spelled)

    a^2 + b^2 = c^2 ... where a and b are the legs and c is the hypotenuse

    3^2 + b^2 = 11^2

    9 + b^2 = 121

    b^2 = 121 - 9

    b^2 = 112 ... take the square root of both sides, eliminating the ^2

    b = square root of 112

    b = 10.58 < = = = the other leg of the triangle
