    90 is hypotenuse, the vertical component v is Cos31 = v/90N

    v = 90N/cos31

    Then double that.

    90*cos 31*6 = W*cos 31*3

    W = 90*2 = 180 N

    Fx = W*cos 31+90*sin 31 ≅ 200 N

    Start by taking the moments of the forces 90N and W about point B to get the weight

    ie : 90  x 6 = W Cos (31) x 3. 

    Then resolve horizontal force to get X
