Use the Cosine Law to find r.
------
r^2 = p^2 + q^2 -2*p*q*cos(50)
=====================
But, r is not the resultant force.
Complete the parallelogram by adding the 2 sides parallel to p and q
Call the resultant force f. f is the long diagonal.
=======
f^2 = p^2 + q^2 -2*p*q*cos(130)
-------------------
Change the values of p and q, calculate f again.
