A plane is flying at an altitude of 12,000 feet and is preparing to land at a nearby airport. The angle from the airport to the plane is 17. To the nearest tenth of a foot, how far is the airport from the plane?

tan 17 ° = H / A

H = A tan 17 °

H = 12,000 * 0.30573

H = 3668.76 ft

H = 3668.8 ft

To the nearest tenth of a foot
