The problem(s) are shown in the link, but I'm having trouble getting them started.

2. Relevant equations

3. The attempt at a solution

For 3-12:

I think what I need to do is find the tension force in the ropes leading from each block to point A. Then with those forces I find the Sum of the forces in X and Y

From there i think i know what to do, its just that i dont know how to find the force in each rope!

My attempt:

For block B, the force in the the rope to point A is sin∅/200lb. For block C, the force in the rope to point a is sin(30)/100 =50lb .

Is this correct so far?
