A primate research station attaches a tiny radio transmitter to a chimpanzee born in captivity before releasing it into the wild. One day, the station picks up a signal indicating the chimp is 3950 m from the station in a direction 15° S of W. Over the next day, the chimp wanders 2500 m in a direction 33° N of E. At this point, how far from the station and in what direction is the chimp?
