a pilot flying at In altitude of 1800 m spots in airplane in the distance he notices that the angle of the depression from the plane to the airport is 22° how far is the plane from the airport in altitude of 1800 m spots an airplane in the distance he notices that the angle of the depression from the plane to the airport is 22° how far is the plane from the airport
Let x be the distance between the plane and the airport. We have, Angle of depression = 22° Altitude = 1800 m Sin 22° = Opposite/Hypotenuse => Sin 22° = Altitude/x => Sin 22° = 1800/x => x × Sin 22° = 1800 => x = 1800/Sin 22° => x = 1800/0.3746065934 => x = 4805.04089 m
