Find: F (parallel)

Solution: sin(<)=opp/hyp

opp =sin(<)(hyp)

F (parallel)=sin(55*)(215 N)

F (parallel)=176.1 N

Gravity is the parallel force that you're solving for because it is the force that makes the box slide down the incline. It's the y-component of weight when drawn on a vector diagram, but it's even understandable as a component of weight because weight=mg.
