Radiolocators
An aircraft took off from airport L, is flying in a straight direction at constant altitude, and is being tracked by two radiolocators placed such that their stations A, B and airport L lie in a line. At the first measurement, the aircraft was registered from station A at an altitude angle of 87° and simultaneously from station B at an altitude angle of 42°. At the second measurement, at station A an altitude angle of 53° was determined, and at station B an altitude angle of 81°. Determine the distance that the aircraft flew between the two measurements, if the distance of the stations A, B equals 6 000 m.
