Question

A right triangle has a hypotenuse that is 21 inches long and a leg that is 15 inches long. How long is the other leg of the triangle?

Answer 1

Answer: In a right triangle, the length of the hypotenuse is the square root of the sum of the squares of the other two legs. So, using the Pythagorean theorem, the other leg would be the square root of (21^2 - 15^2) = (441 - 225) = 216 = 14.69 inches.
