Bob has a helicopter and from the launch pad, he flies the following path. First. he travels from the launch pad a distance of 20km at a heading of 30 degrees East of South (240 degrees). Then he flies 45 km heading 65 degrees West of North (155 degrees). After this, he flies 50 km heading 70 degrees West of North (160 degrees). Now he's ready to return to the launch pad. What is the displacement vector that he needs to take to return directly to the launch pad, from his present location (for the heading, give the # of degrees north of east- your answer may be greater than 90 degrees)?
