A ferry transports tourists between three islands. It sails from the first island to the second island, 4.76 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. Calculate the distance between (a) the second and third islands and (b) the first and third islands.

A ferry transports tourists among three islands. It sails from the first island to the second island, 5.84 km away, in a direction 37.0° north of east. It then sails from the second island to the third island
in a direction 58.5° west of north. Finally, it returns to the first island, sailing in a direction 28.0° east of south.

Two racing boats set out from the same dock and speed away at the same constant speed of 93.9 km/h for half an hour (0.500 h), the
blue boat headed 29.0° south of west, and the green boat headed 38.7° south of west. During this half-hour (a) how much farther west
does the blue boat travel, compared to the green boat, and (b) how much farther south does the green boat travel, compared to the
blue boat? Express your answers in km.
