Answer: A
Step-by-step explanation:
[tex]\stackrel\frown{XY}[/tex] ≅ [tex]\stackrel\frown{YZ}[/tex]
⇒ ∠XOY ≅ ∠ZOY
[tex]\overline{XO}[/tex] ≅ [tex]\overline{ZO}[/tex] since they are both a radius
[tex]\overline{OY}[/tex] ≅ [tex]\overline{OY}[/tex] based on reflexive property
∴ ΔXOY ≅ ΔZOY by SAS
So, [tex]\overline{XY}[/tex] ≅ [tex]\overline{ZY}[/tex] by CPCTC
ZY = 10.2 is given
so, XY = 10.2 by substitution property
