(5 points) Four vectors, A, B, C, and D, are shown in the figure. A and B both have a magnitude of 4.00 cm, and vectors and D both have a magnitude of 7.00 cm (The drawing is for illustration purposes only and not on a scale - so the arrow represent directions properly but the length does not represent the magnitude). Determine the vector sum of these four vectors (use both (a) graphical method and(b) component method). Report you answer for each in form of magnitude and direction. Assume 3 significant figures in all the numbers given in the figure. 450 450 4501 450 C D
