312 degrees is in A q4 so it's going south east

42 degrees east of South with a vector equal to 165. 165sin (42 ) TIMES -1

anonymous · Answer

Why is it east if they are asking how far west the plane is?

tylerd · Answer

It's displacement is negative I guess

tylerd · Answer

Hence the times -1

tylerd · Answer

U could say 110 but whoever wrote the problem is wrong

thomas5267 · Answer

I think the degree here refers to the bearing.  That is, 0 degree = north, 90 degree = east, 180 degree = south and 270 degree =west.
