In the diagram of circle a, what is the measure of ∠xyz? 35° 70° 75° 140°

THIS IS THE BEST ANSWER 👇

First Choice is right.

Step by step explanation:

Oh we gave that

Measurement of arc WZ = 175 °

Measure ∠XAZ = 105 °

We need to get the ∠XYZ measurement.

As we know, the angle located in the center is the mean of the arc measurement intercepted by an angle and its perpendicular angles.

 frac {175 ^  circ +  Angle XYZ} {2} = 105 ^  circ \\ 175 ^  circ +  Angle XYZ = 210 ^  circ \\ angle XYZ = 210 ^  circ- 175 ^  circ \\\ angle XYZ = 35 ^  circ

Hence, the value of ∠XYZ is 35 °.

Hence, First Choice is right.
