A tether ball is attached to the top of a 15-foot pole. Maddy holds the ball 3 feet off the ground and 4 feet from the pole. How long is the rope that the tether ball is attached to?

Answer 1

vertical = 15 -3 = 12
horizontal = 4
hypotenuse^2 = 4^2 + (4*3)^2 = 4^2 + 9 *4^2 = 10 * 4^2
so hypotenuse = 4 sqrt 10

Answer 2

160 ft

Answer 3

160
