--- Quote ---Can any1 help in this question... please.

Its in June 2008 M1 paper question 5.

Two forces P and Q act on a particle at a point O. The force P has magnitude 15 N and
the force Q has magnitude X newtons. The angle between P and Q is 150°, as shown in
Figure 1. The resultant of P and Q is R.

Given that the angle between R and Q is 50°, find
(a) the magnitude of R,   (4)
(b) the value of X.    (5)

the diagram is something like this its in the question :

                     P
                        \
                         \ 
                          \
                           \
                            \._________________ Q
                          O
angles is 150 ^^
