Two forces act on an object. The first force has a magnitude of 360 newtons and acts at an angle of 30° as measured from the horizontal. The second force has a magnitude of 240 newtons and acts at an angle of 135° as measured from the horizontal. Determine the vector v that represents the resultant force.

measured from the horizonal? clockwise, or counterclockwise. It is difficult for me to believe your teacher taught you this sloppiness.
sloppy, but as long as both vectors use the same basis, irrelevant.
v1 = <360 cos30°,360sin30°>
v2 = <240cos145°,240sin145°>
v = v1+v2
