Sara is setting up a volleyball net in her backyard. The poles to hold the net up are 10 feet high. Sara needs to run a wire from the top of the pole to the ground to help make sure that when players hit the net, the pole doesn't fall down.

If Sara runs the wire from the top of the pole to a point on the ground 7 feet from the base of the pole, how long will the wire need to be?

• 15 feet
• 12.21 feet
• 10 feet
• 8.5 feet
