Question 210640: in a right triangle, the leangth of the hypotenuse is 20 inches and the length of one leg is 15 inches. What is the length of the other leg? Answer by Earlsdon(6294) (Show Source):
You can put this solution on YOUR website! Use the Pythagorean theorem: where c is the length of the hypotenuse (20 inches), a is one of the other two legs, it doesn't matter which one so we'll use a = 15 inches. We have to find the length of b. Subtract 225 from both sides. Take the square root of both sides. inches.
