1. The problem statement, all variables and given/known data A ferryboat transports tourists among three islands. It sails from the first island to the second island, 4.02 km away, in a direction 37.0° north of east. It then sails from the second island to the third island in a direction 69.0° west of north. Finally, it returns to the first island, sailing in a direction 28.0° east of south. (a) Calculate the distance between the second and third islands. (b) Calculate the distance between the first and third islands. 2. Relevant equations 3. The attempt at a solution Sadly, I don't know where to start. I know I have to find the x and y components, but don't know how since only one side/distance is given. Any help is appreciated..
