5. Parasailing is an activity in which a person is hamessed to a parachute and towed behind a boat at high speed. The parachute allows the person to rise above the water and fly behind the boat. Sarah
and her brother went parasailing while on vacation this past summer. While her brother was parasailing, Sarah wondered how high above the water's surface he was flying. In order to calculate this
height, she measured how high above the boat the first six inches of tow line had risen. Diagrams of Sarah's brother parasailing and of Sarah's measurements are shown below.
