Anyone know what I'm doing wrong? My answers are in Green :)

A 4.4 N weight is in equilibrium under the influence of the three forces acting on it. The F force acts from above on the left at an angle of A with the horizontal. The 5.4 N force acts from above on the right at an angle of 53 degrees with the horizontal. The force 4.4 N acts straight down.
1) What is the magnitude of the force F? Answer in units of N.
5.4 cos 53 degrees = 3.25 N
3.23^2 + 4.4^2 = 29.9225^2
take the square root of 29.9225 = 5.47 N
2) What is the angle A of the force F? Answer in units of N.
tan-1 (4.4/3.25) = 53.5 N
