And then I figure out, are there any other forces making this system go? You might say, well what about this tension over here?

Isn't the tension on this three kilogram mass? Not really, because that's an internal force exerted between the objects in our system and internal forces are always opposed by another internal force.

a) Find the magnitude of the tension in each cord in terms of α1, α2 and m so that the system is at rest.

b) Find numerical values to the three tensions found above for α1 = 45 , α2 = 30 and m = 1 Kg.
