Net Force problem NEED HELP!

You have to break up each force into its horizontal and vertical components. If F1 is at 30 degrees above the -x axis and I understand what that means, there is a 5.5*sin(30) = 2.75N force downward and a 5.5*cos(30) = 4.76N force in the positive x direction. For F2, the downward force is 3.5*sin(37) = 2.11N and the force in the negative x direction is 2.80N. The surface the block is sitting on is resisting all the vertical forces, so you can ignore them. The imbalance comes from the 4.76N force in the +x direction overcoming the 2.80N force in the -x direction. You need another 1.96N force in the -x direction.
