Vectors help! again

An air traffic controller observes two airplanes approaching the airport. The displacement from the control tower to plane 1 is given by the vector A , which has a magnitude of 220 km 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 140 km and points 65 degrees east of north.sketch the vectors A, B and D=A-B.Notice that vector D is the displacement from plane 2 to plane 1. Find the direction and magnitude of vector D.

please help! my assignment is due tomorrow!!! truth be told, i have NO idea what to do since i have not even learned anything yet and this is a summer assignment

Do as it says - start by drawing a picture of the vectors from the control tower to the two planes. Do you understyand the nomenclature being used: "32 degrees north of west" and "65 degrees east of north"? And are you familiar with how to add vectors? To get vector D take vector B, turn it around, and position the tail at the end of vector A. In effect you are adding the negative of vector B to vector A. Vector D then goes from the start of vector A (at control tower) to the end of this reversed vector B.
