the number on the left is the displacement, on the right is the vector. The person travelling i order of the numbers ....not sure how to explain this because there are no instructions only a shart with the titles of the categories Steps, Displacement, Vector.
I'm supposed to find the Displacement. How do I do that?
20m North
52m South
19m East
30m North
1m West
1m North
10m South
56m North
19m West
26m South

There is no magic but to resolve each and every vector into its components (East =x, North =y), and add up each component.
A well formatted table will help you organize your work. A suitable format could be:
Distance Direction(°) x-component y-component
20 90 20cos(90) 20 sin(90)
52 -90 20cos(-90) 20sin(-90)
....
26 -90 26cos(-90) 26sin(-90)
------------------------------------
Total --- x-total y-total
