1. The problem statement, all variables and given/known data Find the resultant displacement(magnitude and direction of the following vectors: 12.3m North, 45.6m East, 78.9m West, 14.7m South 2. Relevant equations c=sqrt a^2 + b^2 3. The attempt at a solution Do you just add the vectors so the north and south added together will give you 2.4m, etc then use Tan inverse to get the angle? when I did that... I got 33.4m for the magnitude and 85.9 degrees for the direction , however do you need to minus that from 270 to get 184.1 degrees? Am i doing this right?
