Answer:
Option B 34° is the answer.
Step-by-step explanation:
From the inscribed angle theorem, the measure of an inscribed angle is half of the intercepted arc.
Here intercepted arc is xz = 68° and inscibed angle is ∠xyz.
Therefore, by theorem,
∠xyz = [tex]\frac{1}{2}[/tex]m(xz)
∠xyz = [tex]\frac{1}{2}[/tex] (68)°
∠xyz = 34°
Option B 34° is the answer.
