A swimmer heads perpendicular to a 2milesperhour current. His speed in still water is 1.8 miles per hour. Find the actual speed of the swimmer and his direction angle, 0 (the zero right her is supposed to have a line through the middle of it, I think it means cosine or something), with respect to the direction of the current.
