The magnitudes of the four displacement vectors shown in the drawing are A = 10.0 m, B = 11.0 m, C = 12.0 m, and D = 21.

The magnitudes of the four displacement vectors shown in the drawing are A = 10.0 m, B = 11.0 m, C = 12.0 m, and D = 21.0 m. Determine the (a) magnitude and (b) direction for the resultant that occurs when these vectors are added together. Specify the direction as a positive (counterclockwise) angle from the +x axis. I got 15.97 for R and 197 degrees. Correct?
