Question

the length of one leg of a right triangle is 20ft, and the length of the hypotenuse is 52 ft. What is the length of the other leg?

Answer 1

A^2 + b^2 = c^2
20^2 = 400
52^2 = 2704
400 + b^2 = 2704
2704 - 400 = 2304
So you need the square root of 2304 which is 48 so the length of the other leg is 48 ft.
