Using graphical method solve this problem:  Suppose you first walk A in a direction of B west of north then C in a direction D south of west. You rest for 20 minutes and started to compute the distance you traveled. Take A, B, C and D found in the table below. (You may use scale such as 1cm = 2m in your drawing)    A. Sketch the problem in a Cartesian plane.  B. How far are you from your starting point, and what is the compass direction of a line connecting your starting point to your final position (resultant R)?   C. What is the angle between AC ?  D. What is the angle between your first walk A to the resultant R?
