An aircraft is flying at a constant height with a speed of 360 km/h. From a point onthe ground, the angle of elevation of the aircraft at an instant was observed to be 45°.After 20 seconds, the angle of elevation was observed to be 30°. Determine the heightat which the aircraft is flying (use sqrt3 = 1.732).
