Am I heading in the right direction?
If so i am lost now in finding the missing values for the unknown weights, a little nudge would be great. The work that i have attached is CLEANED up so it can be readable.

I finally was able to complete this problem.
First i was going in the wrong direction using unit vectors. I found out that it was a simple force vector problem. Bottom line i was over thing and making it out to be more complicated then it really was, but it was comforting to find out that i was not the only one :-) But anyway I am going to attached my solution. The professor did not use angles in his solution as i did he just used the properties of find the angle sine=opp/hyp and cos=adj/hyp. I used tan to find the angles as you can see. The one that that confuses me is how precise is precise?
Thank you


I am new on here and i see that this would be a good place for practice.
