I am lost. Needing great details and steps please to solve. Thank you

As you will see in a later chapter, forces are vector quantities, and the total force on an object is the vector sum of all forces acting on it. In the figure below, a force F, of magnitude 6.50 units acts on a box at the origin in a direction 0 = 28.0 above the positive x-axis. A second force F, of magnitude 5.00 units acts on the box in the direction of the positive y-axis. Find graphically the magnitude and direction (in degrees counterclockwise from the +x-axis) of the resultant force F , + F , N CO magnitude units direction counterclockwise from the +x-axis
