There is clearly missing information eg. mass of particle. Please post the whole question.

If you assume that the 8N force is just the right amount to offset the component of the gravitational force acting down the plane (i.e., the particle is not moving), I think you can move forward. First off: what coordinate system do you want to use? Since all the forces except the normal force are acting in vertical or horizontal directions, you might prefer that coordinate system.

Try to write Newton's Second Law for all the forces. What forces do you have operating on the particle?
