A golfer, putting on a green, requires three strokes to "hole the ball." During the first putt, the ball rolls 5.8 m due east. For the second putt, the ball travels 2.3 m at an angle 20° north of east. The third putt is 0.50 m due north. What displacement (magnitude and direction relative to due east) would have been needed to "hole the ball" on the very first putt?

Add the three vectors (putt length and direction) to get the answer. It is most easily done by adding components.
You are welcome to ignore my answers. I will do the same with your questions.
