A right triangle has one leg with a length of 48 and a hypotenuse with a length of 80. What is the length of the other leg?

Use the Pythagorean theorem: the squares of the two legs add to the square of the hypotenuse. If the other leg is x, then x² + 48² = 80², so x² = 6,400 − 2,304 = 4,096. Taking the square root gives x = 64, so the other leg is 64, choice B.
