Answer: a. 90°
Step-by-step explanation:
We know that the in a circle, the measure of an inscribed angle is half the measure of the central angle with the same intercepted arc.
In the problem∠XYZ is the inscribed angle
∠XYZ=![\frac{1}{2}\ arc(XZ)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5C%20arc%28XZ%29)
⇒ ∠XYZ=![\frac{1}{2}\angle{XZ}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Cangle%7BXZ%7D)
Since XZ is a diameter of the circle which is a line segment, thus ∠XZ=180°
∴ ∠XYZ=![\frac{1}{2}180^{\circ}=90^{\circ}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D180%5E%7B%5Ccirc%7D%3D90%5E%7B%5Ccirc%7D)
∴ ∠XYZ=![90^{\circ}](https://tex.z-dn.net/?f=90%5E%7B%5Ccirc%7D)
Therefore, a. 90° is the measure of ∠XYZ.
Answer:
