"an air traffic controller observes two airplanes approaching the airport. the displacement from the control tower to plane 1 is given by the vector a⃗ , which has a magnitude of 220 km and points in a direction 32 ∘ north of west. the displacement from the control tower to plane 2 is given by the vector b⃗ , which has a magnitude of 140 km and points 65 ∘ east of north.

sketch the vectors a⃗ , b⃗ , and d⃗ =a⃗ −b⃗ . notice that d⃗ is the displacement from plane 2 to plane 1. draw the vectors with their tails at the dot. the orientation of your vectors will be graded. the exact length of you"
