Suppose the vector F points 17.1 degrees west of north. Then if I were to find angle of this vector with respect to positive x-axis, I add 17.1 degrees and 90 degrees and get 107.1 degrees, right?

On a question that asked to find the angle with respect to positive x-axis, I solved it as stated above, but it's wrong.

What is wrong with my method?

your angle is in the second quadrant. so you should do this 180-17.1 = 162.9 degrees.

I tried 162.9 degrees but I was told it's wrong. It's very frustrating.. :(

The question should explain what it means by "with respect to positive x-axis".

What should I do?
