Find the direction of vector R counterclockwise of the + x axis

    1. The problem statement, all variables and given/known data

    Find the direction of vector R counterclockwise to the + x axis

    2. Relevant equations



    3. The attempt at a solution

    This kind of threw me off balance. I know to get the direction of the vector R for the problem is arctan (5.07/10.87) which gives me 25.

    However the answer is 181 degrees.

    What am I doing wrong?

    Thank you

    So are you saying that R points in the negative x axis direction?
    Or are there more facts to this problem?
