A commuter airplane starts from an airport and takes the route shown in Figure P3.17. It first flies to city A located at 227.5 km in a direction 30.0° north of east. Next, it flies 195 km 20.0° west of north to city B. Finally, it flies 247 km due west to city C. Find the location of city C relative to the location of the starting point. A) km (distance from the starting point) B) ° west of north (angle from the starting point) I'm not asking for people to do it for me, just show me where to start -- I don't really understand how to do it.. The teacher didn't really help me.
