Question 611923: Charlie is at a small airfield watching for the approach of a small plane with engine trouble. He sees the plane at an angle of elevation of 32 . At the same time, the pilot radios Charlie and reports the plane�s altitude is 1,700 feet. Charlie�s eyes are 5.2 feet from the ground. Draw a sketch of this situation (you do not need to submit the sketch).

Find the ground distance from Charlie to the plane. Explain your work.

an(x) = opposite over adjacent
tan(32) = (1,700 - 5.2) / x
x tan(32) = 1,694.8
x = 1,694.8/ (tan(32))
x = 2712.25 feet
