 Question 207494: I need help with this question. The hypotenuse of a right triangle is 8 feet less than three times the shorter leg and the longer leg is 8 feet more than twice the shorter leg. Find the lengths of the three sides of the triangle Answer by scott8148(6628)   (Show Source): You can put this solution on YOUR website!let x=shorter leg by Pythagoras ___ x^2 + (2x + 8)^2 = (3x - 8)^2 x^2 + 4x^2 + 32x + 64 = 9x^2 - 48x + 64 0 = 4x^2 - 80x = x^2 - 20x = x (x - 20) x = 0 ___ not a realistic solution x - 20 = 0 ___ x = 20 longer leg ___ 2(20) + 8 ___ 48 hypot ___ 3(20) - 8 ___ 52
