havent I answered this? Convert the angles measured from x axis counter clockwise. assuming your East direction is x axis..
a. angle is 20+90
b. angle is 90
c. 180+35
d. 360-50
Multiple Concept Example 9 provides background pertinent to this problem. The magnitudes of the four displacement vectors shown in the drawing are A = 17.0 m, B = 10.0 m, C = 11.0 m, and D = 23.0 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.
A: direction is west of north with a degree of 20.0
B: direction is north of center no degree
C: direction is south of west with a degree of 35.0
D: direction is south of east with a degree of 50.0
