Angle of vectors?

given vectors A= 3.20 m at 90degrees


B=4.85 m @ 180degrees


C=1.30 m @ 270 degrees


ok i found magnitude of the displacement, which equals 5.21 m.. i am having trouble finding the direction.. i use arctan Ry/Rx. and i get 21.4 degrees, but the system says its wrong. if you could please tell me my mistake. thank you:)

Angle of vectors?
Subtract 21.4 from 180degree to get the angle from the x – axis and in counterclockwise direction.





158.61°
