Two airplanes leave an airport at the same time. An hour later, the planes are 203 km apart. If one plane has traveled 286 km and the other has traveled 180 km during the hour, find the angle between their flight paths. See the figure below. 203 km 180 km 0 286 km Airport Carry your intermediate computations to at least four decimal places. Round your answer to the nearest tenth of a degree. 0°
