I am doing my physics homework and am stuck on this one problem. can anyone help me please?

Two blocks are connected by a massless string and are held in position by another massless string along a frictionless incline (as shown in the figure). Let M1 = 58.0 kg, M2 = 65.0 kg, and θ = 39°. Calculate the tension in the string connecting the two blocks.
I have drawn it out and every thing and have tried using Sin and cosine and keep getting my it wrong.
