See the image for the solutions. I guessed five displacements in the table, provided that vector diagram is shown to visualize the locations.
Hints:
If the vector lies on the first quadrant, then its components have +x and +y.
If the vector lies on the second quadrant, then its components have −x and +y.
If the vector lies on the third quadrant, then its components have −x and −y.
If the vector lies on the fourth quadrant, then its components have +x and −y.
If the angle is relative to the horizontal axis, use cosine for the x-component, and use sine for the y-component.
If the angle is relative to the vertical axis, use sine for the x-component and use cosine for the y-component.
If the angle goes counterclockwise, then the angle is positive.
If the angle goes clockwise, then the angle is negative. It is equivalent by subtracting from 360 degrees to the clockwise angle, to make counterclockwise angle.
Familiarize the cardinal direction on how it describes the direction of the magnitude and angle. Let's say for example, 2 km, 50° N of E; it means that 2 km rotates with the angle 50° starting from east to north.
