Finding normal force - friction

  1. Nov 3, 2007 #1
    1. The problem statement, all variables and given/known data

    the pic is in the attachment. and i am supposed to find the normal force. the object is in equilibrium.


    3. The attempt at a solution

    i tried to separate the Fg into its components but the angle is unknown. i cant seem to use any other method. force of friction is unknown and so is the coefficient.
