Vectors and directional angle...?

C:\Documents and Settings\sdelgado\My Documents\My Pictures\p1-42.gif





The magnitudes of the four displacement vectors shown in the drawing are A = 16.0 m, B = 11.0 m, C = 12.0 m, and D = 16.0 m. Determine the magnitude and directional angle for the resultant that occurs when these vectors are added together.





I was able to find the magnitude, and I know that you're supposed to take the arctan of the total Y/total X values, but for some reason, it's not coming out right. If someone could tell me what I'm doing wrong, I would appreciate it :)

we need to see the picture. we cannot access your picture from our computers the way you have it listed.
