    A)26 degree
    B)29 degree
    C)61 degree
    D)64 degree
    E)241 degree

    2. Relevant equations

    3. The attempt at a solution

    Have you not learned trigonometry yet? What do you not understand here? Explain what is giving you trouble!

    SOHCAHTOA would be useful to use in this problem.

    All of your posts have to do with the same basic thing, vector addition. Did you take any notes on this or do you have a textbook that you use in the class where you could review the concepts?

    Man oh man, every single one of your posts shows no relevant equations and no attempt at a solution. How black is your soul, really?

    This is a forum for physics *help*. Not cheating. There are other websites for that. Actually, there are advertisements for such websites on this forum so...
