Since y is between x and z, so
XZ is the total length of XY and YZ
[tex]XZ=XY+YZ[/tex]Since XZ = 3 inches
YZ = 1 5/8 = 1.625 inches
Substitute them in the equation above
[tex]3=XY+1.625[/tex]Subtract 1.625 from both sides to find XY
[tex]\begin{gathered} 3-1.625=XY+1.625-1.625 \\ 1.375=XY \end{gathered}[/tex]XY = 1.375 = 1 3/8
