In this problem, we have a right triangle where $a$ and $b$ are the lengths of the two short sides, and $c$ is the hypotenuse. Use the Pythagorean Theorem to compute the missing lengths. Assume also that $A$ denotes the angle opposite $a$, $B$ the angle opposite $b$, and, of course, $C$ the right angle.
