A student inscribes a triangle within a semicircle. What is the measure of ∠XYZ?
nata0808 [166]

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)

⇒ ∠XYZ=\frac{1}{2}\angle{XZ}

Since XZ is a diameter of the circle which is a line segment, thus ∠XZ=180°

∴ ∠XYZ=\frac{1}{2}180^{\circ}=90^{\circ}

∴ ∠XYZ=90^{\circ}

Therefore, a. 90° is the measure of ∠XYZ.
