Yes.
One may wish to break the forces into their orthogonal projections. (North-South and East-West) It should be relatively obvious from there.
A force of 36N pulls at an angle of 20 degrees above due east. Pulling in the opposite direction is a force of 48N acting at an angle of 42 degrees below due west. Find the magnitude and direction of the resultant force.
To start off, should I add or subtract the vectors?
Now I'm confused. I thought 42 degrees west (left) of north would be 132 degrees because it would be 90 + 42.
And if I started at the negative x-axis (or "due west"), wouldn't I be making a 180 degree angle? If I were making a 270 degree angle, I would be starting at the negative y-axis.
