Find the tension in each cable necessary to keep the block from moving (either sideways or downward)

A 900-lb block is being suspended and held stationary by two steel cables as shown.  The first cable (to the left of the block) makes a 70 degree angle with the horizontal, while the second cable (to the right of the block) makes a 65 degree angle with the horizontal.  At point B (where the weight is being held), there are three forces acting: R, S, and W.  Find the tension in each cable necessary to keep the block from moving (either sideways or downward).

Please try to explain the steps.
I know so far, Area=1/2absin(angle c)
(8)(6)(1/2(x)(x)sin60)=1590

That was a lot to take in, I appreciate you typing it all.  To be sure of my answers, what did you get as the solutions then?
