[tex]\begin{gathered} m\angle SYZ=34.2 \\ m\angle XYZ=68.4\text{ degr}ees\text{ } \end{gathered}[/tex]
Explanation
Step 1
bisectro is s the line or line segment that divides the angle into two equal parts,so
[tex]\begin{gathered} m\angle XYS=m\angle SYZ \\ \text{replace} \\ 34.2=m\angle SYZ \end{gathered}[/tex]
Step 2
angle XYZ
[tex]\begin{gathered} m\angle XYZ=m\angle XYS+m\angle SYZ \\ \text{replace} \\ m\angle XYZ=34.2+34.2 \\ m\angle XYZ=68.4\text{ degr}ees\text{ } \end{gathered}[/tex]
I hope this helps you
