It is a very simple question involves basic knowledge. Use the concept of vector. In this question use the formulas for force making angle with all three axis i.e. the cosine one. Find vector F, vector OP and write other forces in vector form. Since particle is in equilibrium add all forces and equate to 0.

Thank you. @Gaurav Kumar. But how can I find the one for the z-axis. That is for vector F, I could only find the angles for the x and y- axes. Thank you in advance.
