1. The problem statement, all variables and given/known data
Using the uploaded picture we have to have a force diagram. And we have to break angled forces into components and indicate which forces are equal with equality. All the masses are up to me (2, 3, 4, 5 kgs)

2. Relevant equations
Write an equation for the vertical forces
Write an equation for the horizontal forces
Determine the tension

I hope someone can help me I am seriously confused!!!!

Start with free-body diagrams for each of the nodes.
You also need to write down the other constraints on the system - what you have written is incomplete.
i.e. if the masses are up to you, then imagine the far right mass is 1000000kg and all the rest are 1g.

Welcome to PF! Draw the forces acting on each mass. Also draw the tensions at the nodes of the ropes. Show your picture, but not as PDF file.
