A grasshopper makes four jumps. The displacement vectors are (1) 25 cm, due west; (2) 23.5 cm, 50° south of west; (3) 24.5 cm, 56° south of east; and (4) 36 cm, 43° north of east. Find the magnitude and direction of the resultant displacement. Express the direction with respect to due west. (Positive is counterclockwise from due west.)
