Vector addition simple question

  1. May 22, 2014 #1
    There seems to be problem with the answer to this problem. Weirdly, they get that the x component of F1 is 3N!

    Then, when they end up calculating the direction in C, they get 9.5°. I get 9.16°.

    Am I the one going crazy? This is fairly straight-forward!

    From the 31 "they"calculate, I conclude that F1x is 7N in their calculations. (I get 31.4)
    You and I get 9.16 degrees, perhaps "they" write it as 9 degrees 5 minutes ? (I 9° and 6')

    Wouldn't worry too much about this, you're no crazier than I am!
