<p>This is XXXX from your CHM 331 class. I have a question about
part c from your homework problems. Since we need to find the
magnitude and direction, I think I would have to do a little
trig to figure it out. However, I am not sure how to do this
without knowing the value of the angles. What am I doing
incorrectly? </p>

You are correct! You do have to do a little trig to figure out the
angles you need. When I solved this problem I sketched the system
in an x-y coordinate system and that greatly simplified determining
the angles.<br>
