1. The problem statement, all variables and given/known data Hello, I have a homework question that I'm having difficulty with, it is: A car travels due east (bearing 90) from point A for 6km to point B and then North-west (bearing 315) for 4.0km to point C. By constructing a vector diagram, or otherwise, find the resultant displacement (magnitude and direction) of the car at point C from A. 2. Relevant equations I don't think pythagoras theorem works here, as there is no right-angled triangle present. Although, I may be incorrect. 3. The attempt at a solution I've drawn a vector diagram, head to tail, and measured the displacement, it comes to 4.3km at a bearing of 50. Is that correct?
