Ok i finally begin to understand the resultant force questions and im hit with this one.

6. the diagram shows a body of mass 6kg suspended in equilibrium by two light inextensible strings AC and BC, attached to two fixed point A and B on the same horizontal level. The strings AC and BC are inclined at angles 45° and 60° to the horizontal respectively.

Find the tension in the string AC and the tension in the string BC.

Ok i really do not know how to do this.

I'm assuming you use sine and cos to do it but im not sure how at all. Could anybody at least start me off?

thanks
