It's the square root of both sides squared, ?= sqrt of side one squared +
side two squared. Its called the Pythagorean Theorem a2 + b2 = c2 . You need
to take the square root of c2 to get c

In your case 53.75.

It's been way too many years since I was in a math class and need help.

If I have a triangle that has one side at 39ft, the 2nd side is 37 ft. and
they meet at a right angle, how long is the third side?
Many thanks!
