2 Practice the Pythagorean Theorem The base of a ladder is placed 6 feet from a wall. If the top of the ladder rests 8 feet up on the wall, how long is the ladder? 6 feet 8 feet ? feet a 2 + b 2 = c = c = c = c 2 10 = c The length of the ladder is 10 feet.

3 Donna's TV screen is 20 inches long. If the diagonal measures 25 inches, how long is the width of Donna's TV? Practice the Pythagorean Theorem 20 inches 25 inches ? inches a 2 + b 2 = c b 2 = b 2 = 625 b 2 = 225 b = 15 The width of the TV is 15 inches.
