A patrol car is parked parallel to the zone, 200 feet from one end and 150 feet from the other end (see figure). Enforcement zone 200 ft 150 ft A B Not drawn to scale T (a) Find the length / (in ft) of the zone and the measures of the angles A and B (in degrees). (Round your answers to two decimal places.) A- B = ft (b) Find the minimum amount of time (in seconds) it takes for a vehicle to pass through the zone without exceeding the posted speed limit of 30 miles per hour.
