An airplane flying at an altitude of 6 miles is on a flight path that passes directly over an observer. If thêta is the angle of elevation from the observer to the plane, find the distance from the observer to the plane when (a) thêta = 30°, (b) thêta = 90°, and (c) thêta = 120°. Show work for each step.
