A Coast Guard cutter detects an unidentified ship at a distance of 18 km in the direction 16.2° east of north. The ship is traveling at 22.5 km/h on a course at 36.2° east of north. The Coast Guard wishes to send a speedboat to intercept the vessel and investigate it. If the speedboat travels 46.4 km/h, in what direction should it head? Express the direction as a compass bearing with respect to due north.
I know that diagrams can't be drawn on this site, but can anyone try to explain this picture? I don't even know where to begin or what equations to use.
