A basketball player runs down the court, following the path indicated by the vectors {rm vec A}, {rm vec B}, and {rm vec C} in the figure. The magnitudes of these three vectors are A,=,10.0,{rm m}, B,=,20.0,{rm m} and C,=,7.0,{rm m}. Assume the positive x axis is directed to the right. Find the magnitude and direction of the net displacement of the player using the graphical method.
