A frisbee landed on the roof of the house. The place where you have decided to place the ladder is right over the AC unit, forcing the base of the ladder to be 8ft from the side of the house. If the house is 15ft tall, how long must the ladder be to ensure it reaches the roof? That length will only ensure the ladder reaches the roof exactly. Add 1 extra foot, then tell me the length of the ladder that you would buy?
