The hypotenuse of a right triangle is 52 in. One leg of the triangle is 8 in. more than twice the length of the other. What is the perimeter of the triangle?

Let the shorter leg be x inches, so the other leg is 2x + 8 inches. By the Pythagorean theorem, x² + (2x + 8)² = 52², which gives x = 20; the other leg is 48. The perimeter is 20 + 48 + 52 = 120 inches, so the correct choice is 120 in.
