How to solve this vector problem??? 1. The problem statement, all variables and given/known data A car travels 20 km due north and then 35 km in a direction of 60degree west of north. Find the magnitude and direction of a single vector that gives the net effect of the car trip. 2. Relevant equations (vector) R = square root (vector)( A^2 + B^2) 3. The attempt at a solution I found the answer is 40.1 km while the answer says it's 48 km. I don't know how to solve the angle. Help please!!!
