Start with a Free Body Diagram

The only formula you will ever need is F = ma, and some trig skills

i think the forces are gravity, tension and frictional.

What do you mean you "think" there is friction? That's actually important...

um because its touching the surface

Does the problem state there is friction? We don't want to add anything we don't want

it says " the coefficients of kinetic friction and static friction between the left hand box and the plane are .15 and .30"

Wellllllllll wouldn't that be great if you told us that from the start?

You still haven't provided us a Free Body Diagram. It's good you know what forces are present, but what forces are acting on each body?
