1. The problem statement, all variables and given/known data Find the direction angle of vector <-2,-5> 2. Relevant equations The components of a vector is v=<magnitude*cos ø, magnitude*sin ø> Magnitude of a vector: √(a^2+b^2) 3. The attempt at a solution I found the magnitude of the vector, which is √29. Then I set -2= √29 cos ø and solved for ø. It was 111.891 degrees but the answer to the problem was 360 MINUS 111.891 degrees. I thought it would be 180 PLUS 111.891.
