Statics-Resultant Question

  1. Jan 25, 2010 #1
    1. The problem statement, all variables and given/known data
    I have attached the problem from the book. It is asking to determine the magnitude and direction of the resultant.

    2. Relevant equations
    Law of Sines
    Law of Cosines

    3. The attempt at a solution
    I have started out by using the Parallelogram Law to draw the resultant and I'm pretty sure I could solve this problem with the law of cosines and sines, but I am having trouble figuring out the angles I need to use. Any help would be appreciated..

    Why not break up each force into its x and y components? Then sum the x components to get R_x, , sum the y components to get R_y, then R =????? , and the angle that R makes with the x axis is ?????
