2. Relevant equations

3. The attempt at a solution

I found Fx = 1.7 N and Fy = 3.3 N. So the total magnitude was 3.3 N. This part was correct, however when I tried to find the magnitude usting tan^-1(Fy/Fx) = tan^-1(3.3/1.7) = 62.74 degress the answer is wrong. It says I'm within 10%, but still wrong. I don't understand why. Please help
