Let c represent the length of the hypotenuse of a right triangle, and let a and b represent the lengths of its legs, as pictured in the image that follows. The sum of the squares of the legs should equal the square of the hypotenuse. The length of one leg of a right triangle is 15 meters, and the length of the hypotenuse is 25 meters.
