Homework Statement
I'm having trouble understanding how to find the angle of a vector. Here we are given the x and y component to help us find the direction of vector C. In this case, both x and y component is negative, so it should be in the third quadrant. I know that since we have both the x and y component, we need to use inverse tangent, and since the vector is in the third quadrant we add 180 to the inverse tangent as shown in part 3 because the vector is past 180, but before 270. My question is if the vector is in the second quadrant, would we add 90 to inverse tangent? If the vector is in the fourth quadrant, would we add 270 to inverse tangent? This is seriously frustrating me.

It's all in part 3.
