Lets do them in N, E vectors
R=-12N+8cos20 N +8sin20 E
figure that out.
then magnitude will be
R^2=N^2+ E^2
and the angle will be arctan(E/N) (E of S) (in the SE quadrant)
R=-12N+8cos20 N +8sin20 E
figure that out.
then magnitude will be
R^2=N^2+ E^2
and the angle will be arctan(E/N) (E of S) (in the SE quadrant)
