Fnet=ƩFi=0

The Attempt at a Solution

I am not sure about the right way to find the angle but the variables given are force and the mass should I use the weight to find the angle? Is this a obtuse triangle?

The only thing my professor told me when I had difficulty with these types of problems was to use components. I would recommend drawing a picture or diagram with all the forces acting on the mass, that should make it easier to solve.
