3. The angle of depression of a buoy from the top of a lighthouse 130 feet above the surface of the water is 6°. Find the distance x from the base of the lighthouse to the buoy. tan Θ = tan 6° = 130 x x = ≈ 1,236.9 130 tan 6° To the nearest foot, the buoy is 1,237 feet from the base of the lighthouse 130 6° Θ x
4. From the top of the 100-ft-tall building a man observes a car moving toward the building. If the angle of depression of the car changes from 22° to 46 ° during the period of observation, how far does the car travel? The car travels about 151 feet. 46° 22° 22° 46° 100’ x d
