Final answer:
The length of the line segment WZ is closest to 4.1 units.
Step-by-step explanation:
To find the length of the line segment WZ, we can use the distance formula. The distance formula is √((x2-x1)^2 + (y2-y1)^2), where (x1, y1) and (x2, y2) are the coordinates of the endpoints.
Substituting the given coordinates, we get √((2-6)^2 + (5-4)^2) = √((-4)^2 + (1)^2) = √(16 + 1) = √17. Therefore, the length of WZ is closest to √17 which is between 4 and 5. The measurement closest to the length of WZ in units is 4.1, option d.
