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
