- Pythagorean Theorem & sin cos tan

In the figure below, a highway rest area (at D) and radar stations (at A and B) lie on a level east-west line; A is 9,000 feet due west of D. An airplane (at C) is shown directly above the rest area, flying due west at a constant speed of 300 feet per second and at a constant altitude of 12,000 feet. The airplane is located at,a straight-line distance of 15,000 feet from the radar station at A and 13,000 feet from the radar station at B.
