An airplane leaves City A and flies 144 km due north to City B. It then turns through an angle of 49° and flies 96 km to City C. What angle with respect to due north could the pilot have used to fly directly from City A to City C? See the figure below. City C 96 km 0 City A Carry your intermediate computations to at least four decimal places. Round your answer to the nearest tenth of a degree. x S City B 144 km 0° 49°
