From the present figure, we can conclude that the distance from W to Y must be equal the sum of the distance from W to X with the disctance from X to Y, because it is a straight line. From this, we can write a math relation as follows:
[tex]WY=WX+XY[/tex]
We know the distance from X to Y (XY) and from W to Y (WY). Substituting these values into the relation we have, we cansolve it as follows:
[tex]\begin{gathered} 100\operatorname{cm}=WX+89.6\operatorname{cm} \\ WY=100\operatorname{cm}-89,6\operatorname{cm} \\ \\ WY=10.4\operatorname{cm} \end{gathered}[/tex]
From the above solution, we conclude that the correct answer is the second option: 10.4 cm
