The angle of elevation is the angle formed by a horizontal line and a line joining the observer’s eye to an object above the horizontal line. A person is 1000 feet way from the launch point of a hot air balloon. The hot air balloon is starting to come back down at a rate of 5 ft/sec. At what rate is the angle of elevation, θ, changing when the hot air balloon is 400 feet above the ground
