It involves a diagram as well which I've posted a screenshot of but sure here 

The diagram shows three particles A, B and C hanging freely in equilibrium, each being attached to the end of a string. The other ends of the three strings are tied together and are at the point X. The strings carrying A and C pass over smooth fixed horizontal pegs P1 and P2 respectively. The weights of A, B and C are 5.5 N, 7.3 N and W N respectively, and the angle P1XP2 is a right angle. Find the angle AP1X and the value of W.

since the system is in equilibrium, we would have to ascertain the sum of the sin and cos parts to cancel them out
