A right triangle has three sides: the two sides that share a vertex are known as the legs, and the other side is known as the hypotenuse. The legs are known as a and b, while the hypotenuse is c. The Pythagorean Theorem states the a^2 + b^2 = c^2. If we plug the numbers into this equation, we will find the length of the hypotenuse. 39^2 + 80^2 = c^2 1521 + 6400 = c^2 7921 = c^2 We have c squared now, but we want to know how much c is equal to. The square root of c^2 will be our answer. 89 = c The length of the hypotenuse of a right triangle with legs that measure 39 and 80 inches is 89 inches.
