4. An airplane uses a radio beacon transmitting from an airport to determine how far off course it is from its flight plan to the airport. The pilot takes his first reading and finds that the angle to the beacon o be 25 degrees. Ten miles later the pilot reads the angle to be 40 degrees. How far away is the beacon, and hence the airport, at the time of the second reading? Beacon = Actual location of airport Planes course 250 40° Supposedly the direction of airport Location at first reading Location at second reading
