If the hypotenuse of a right triangle is 122 inches long and another side of the triangle is 22 inches long. how long is the remaining side?

Use the Pythagorean theorem to answer this question. In a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides. The equation usually looks like this: c2 = a2 + b2, where c is the hypotenuse; a and b are the other two sides. In this example, 1222 = 222 + b2. Solving for b, b2 = 14884 - 484, b2 = 14,400, b = square root of 14,400 or 120.
