A man walks 10.1221 m directed 124.9264 degrees from the positive x-axis, then he walks 37.6981 m directed 282.6363 degrees from the positive x-axis, then finally he walks 13.7601 m directed 151.8091 degrees from the positive x-axis. How far he is now from his starting point? Express your answers accurate to four decimal places. Enter only the numerical value
A helicopter starts from an airport and takes the route described. The plane first flies to city A, located 175km away in a direction 30.0o north of east. Next, it flies for 150km 20.0o west of north, to city B. Finally, the plane flies 190 km due west, to city C. Find the distance of city C relative to starting point.
(Write your final answer in 3 significant figures, include the unit in your final answer)
