A small plane is 4 miles by land away from the airport. The angle of elevation from the airport to the airplane is 6.5 Degrees. What is the altitude of the plane? Round your answer to the nearest tenth of a mile.
We have to calculate the altitude of the plane. tan 6.5° = h / 4 miles h = tan 6.5° · 4 miles h = 0.113965 · 4 miles = 0.455742 ≈ 0.46 Answer: B ) 0.46 miles.
