It is problem 15

I drew my free body diagrams, but I can't figure out the relationship to write for the pulley since the incline is frictionless. I know that angular accleration = (M1*g*sin(theta) - M2*g)R/ (I +M2R^2 +M1*R^2)

How do I get there though? I have to somehow get T1 and T2 out of the problem to write everything in terms of M1,M2,I,R,and theta. However, I am missing an important piece because I don't know the relationship between the forces for the pulley.
