Newtons Law Problem: objects and pulleys

[wegman14]

Homework Statement

three blocks attatched by cords that loop over frictionless pulleys. Block B lies on frictionless table, block a hangs off the left side of the table, while block c hangs off the right side. mass a= 6kg mass b= 8kg and mass c= 10kg. When the blocks are released, what is the tension in the cord at the right?

Homework Equations

F=ma
Tension force= mgcos0

The Attempt at a Solution

i don't really have an attempt at the solution, i don't see where to go when only given the masses of the objects. Also, there is no angles involved so it eliminates some of my equations

What else do you feel you need apart from the masses to proceed toward a solution? If angles had been given, how would you have set up the equations? Give an example, so that we can consider it further.
