Answer: [tex]150^{\circ}[/tex]
Step-by-step explanation:
To convert a radian measure to degrees , we generally multiply it by 180° and divide it by [tex]\pi[/tex].
Given : [tex]m. \overarc{XYZ}=\dfrac{5\pi}{6}\text{radian}[/tex]
Then, In degrees it should be
[tex]m. \overarc{XYZ}=\dfrac{5\pi}{6}\times\dfrac{180^{\circ}}{\pi}\\\\\Rightarrow m.\overarc{XYZ}=150^{\circ}[/tex]
Hence, the correct answer is [tex]150^{\circ}[/tex].
