Man, my online physics course sucks. Every time there is a lab or an assignment, it's on stuff I haven't done, lol. Anyway I have an angle of 155 degrees separating one 18 N vector going 85 degrees northwest, and another vector going about 60 degrees southwest. The other angle is 12 N. I have to add them, somehow, and give the magnitude of the new vector and its angle. Then I take my new answer and use it to find the angle between it and another angle, which I already know. I should be able to do that easily enough with the protractor. I have only been taught to add vectors which create right trangles, any way to solve it with right triangles would be great.
