An airplane flies from city A to city B, a distance of 150 miles, and then turns through an angle of 0 = 40 and heads toward city C, as shown in the figure. (a) If the distance between cities A and C is L = 390 miles, how far is it from city B to city C? (b) Through what angle should the pilot turn at city C to return to city A? A 150 mi B (a) The distance from city B to city C is approximately | miles. (Round to two decimal places as needed.) (b) To return to city A the pilot must turn through an angle q of approximately (Round to one decimal place as needed.)
