Newton's Law, tension, blocks, pulleys at an angle, friction

Hi all,
I'm really stumped at this question five of my assignment. Could anyone please give me some help? I don't even know where to start.

Thanks

Start by drawing yourself free body diagrams for each mass. Apply Newton's 2nd law to each.

(The peg can be thought of as a pulley, if that helps.)
