In a right triangle with integer length sides, the hypotenuse has length 39 units. How many units is the length of the shorter leg?

Notice that one possible "Pythagorean Triple" right triangle is one with the sides 5 - 12 - 13

Any any multiple of these will also be a Pythagorean Triple...so....this implies that

5(3) - 12(3) - 13(3) =

15 - 36 - 39 will also be a Pythagorean Triple

So....the shorter leg = 15 units
