SolutionSoltuion:
From the question, the given value id
[tex]\begin{gathered} XQ=3 \\ XR=RW \\ XR+RW=XW \\ XQ=QY \\ XQ+QY=XY \end{gathered}[/tex]
By applying the theorem above, we will have the value of XY be
[tex]\begin{gathered} XQ+QY=XY \\ XQ=3 \\ QY=3 \\ XY=3+3 \\ XY=6 \end{gathered}[/tex]
Hence,
The final answer = 6
