Final answer:
The length of segment XY is calculated by subtracting the length of segment WX from the length of segment WY, resulting in XY being 6 units long.
Step-by-step explanation:
To determine the length of segment XY, we can use the information given that point X is online segment WY. We are told that WY = 16 units and WX = 10 units. Since X lies on the line segment WY, XY is the remaining portion of the segment after WX is accounted for. Hence, the length of XY is simply the difference between the lengths of WY and WX:
XY = WY - WX
XY = 16 units - 10 units
XY = 6 units
This means that the length of segment XY is 6 units.
