A ferry transports tourists among three islands. It sails from the first island to the second island, 5.89 km away, in a direction 37.0 north of east. It then sails from the second island to the third island in a direction 74.5° 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. km (b) Calculate the distance between the first and third islands. km

An airplane flies 200 km due west from city A to city B and then 285 km in the direction of 33.0° north of west from city B to city C. (a) In straight-line distance, how far is city C from city A? km(b) Relative to city A, in what direction is city C? ° north of west

Vector A: Magnitude: .6769 N, angle: 0 degrees Vector B: Magnitude: 1.265 N, angle: 140 degrees Vector C: Magnitude: .7358 N, angle: 235 degrees Vector D: Magnitude: .7063, angle: 340 degrees   Create a diagram and use vector polygon to find the resultant vector.
