Answer:

The length of XY is 17

Step-by-step explanation:

Given that X is midpoint of line WY

WX=3x-1

WY=10x-26

To find XY:

Given WY is straight line and X is midpoint of line WY

We can write as

WX+XY=WY

(3x-1)+XY=(10x-26)

XY=7x-25

Also, WX=XY

(3x-1)=(7x-25)

-1+25=7x-3x

4x=24

x=6

The length of XY is 7x-25=7(6)-25=42-25=17
