Answer:
B) 1/2 (154° - 46°)
Explanation:
Here ∠XYZ is an angle subtended by two chords from a point outside of the circle.
It is a one of the circle.
If the angle subtended by two chords from the outside point of the circle, the measure of the angle is 1/2 times difference of the major arc and minor arc.
Here Major arc = 154° and minor arc = 46°
Applying the rule, we get
m∠XYZ =

m∠XYZ = 1/2 (154° - 46°)
