Examine the Pythagorean theorem below . In this form you can find the length of the hypotenuse (c) of a right triangle if you know the lengths of the two short sides (a & b). Solve this equation for the short side b. If you need to indicate a square root in your answer, type it like this: root * (e + f) to mean the square root of the sum (e + f) . For example, the equation below can be typed as C=root(a^ ^ 2+b^ ^ 2) *
