In calculating OA, you established that the positive x-axis was east and the positive y-axis is north. That means that any movement to the west or south is negative.
 
i don't get it ,can you explain which one i did wrong ?thanks
 
i got dx= -181.6 dy= 72, you was right, i have change bx= -400 and cy -188

please check if i 'm wrong
