A patrol car is parked 65 feet from a long warehouse . The revolving light on top of the car turns at a rate of 20 revolutions per minute. How fast is the light beam moving along the wall when the beam makes angles of 0 = 45°, B = 60°, and B = 85° with the line perpendicular from the light to the wall? (Round your answers to two decimal places.)
(a) θ = 45°
(b) θ = 60°
(c) θ = 85°
