(1 point) A plane flying with a constant speed of 19 km/min passes over a ground radar station at an altitude of 12 km and climbs at an angle of 40 degrees. At what rate is the distance from the plane to the radar station increasing 5 minutes later? The distance is increasing at Hint: Hint: The law of cosines for a triangle is km/min. c²=a² + b² - 2ab cos(0) where is the angle between the sides of length a and b.
