An air traffic controller observes two airplanes approaching the airport. The displacement from the control tower to plane 1 is given by vector A, which has the magnitude 220km and points in a direction 32(degrees) north of west. The displacement from the control tower to plane 2 is given by the vector B, which has a magnitude of 140km and points 65(degrees) east of north. Find the magnitude and direction of vector C. I understand that it needs to be broken up into its components, but I am unable to get the answer (320km @ 10(degrees) north of west). Thanks for any help.
