    R is resultant right so get the horizontal resultant Rx =(x + 15cos30) and Ry= 15sin30
    50= (Ry/Rx)
    But total resultant/magnitude= square root(Ry^2 + Rx^2)

    50=arc tan (Ry/Rx)

    I personally think the easiest way to approach this question is to draw a vector triangle and then use the sine rule in order to work out R, and then do the same thing to work out X.

    Split all the forces into vertical and horizontal components

    Force Q is horizontal only so the vertical component of the resultant force (R) is equal to the vertical component of force P. Therefore Rsin50 = 15sin30 and you can solve that to get R = 9.79055N

    Then,you need to do Rcos50 = Q - 15cos30
    Since you know R already, just solve to get Q = 19.2832N

    I attached my written solution as well
