A golfer takes three putts to get her ball into the hole once she is on the green. Her first putt displaces the ball 71.0 ft north; the second, 6.0 ft, 45 degrees south of east; and the third, 3.0 ft, 45 degrees south of west. What is the magnitude of the displacement (in feet) that would have been needed to get the ball into the hole on the first putt?
