Do I need to use MGSin(theta) if there is a rope with tension on both sides? block is on inclined ramp?

I have a physics homework problem that has 2 blocks on an inclined surface, thats frictionless. Block 1 is attached to Block 2 which is attached to a mass thats hanging from a pulley. The whole system is frictionless, ignore mass of ropes, and its all at rest. I understand that for Block 1, I have MgSin(theta) countering the Tenstion (T1) But for the 2nd block it has a rope on each side (one to hanging mass, and one holding block 1) So there is a T (tension) on both sides. These counter each other but because the block is on an incline do I still add MgSin(theta)? Mass would be for 2nd block in that one. I would get something like Tension 2 - Tension 1 - MgSin(theta) = 0
