Which of the following best describes XYZ
Alex787 [66]
<h2>Answer:</h2>

D. Inscribed angle

<h2>Step-by-step explanation:</h2>

An inscribed angle has a vertex on the circumference. For any arc, every inscribed angle is exactly half of the central angle. In other words, if the central angle is x^{\circ} and the inscribed angles is y^{\circ}, then it is true that:

y^{\circ}=\frac{x^{\circ}}{2}

In this problem y^{\circ}=36^{\circ}, then the central angle is x^{\circ}=2y^{\circ} \ \therefore x^{\circ}=2(36^{\circ}) \therefore x^{\circ}=72^{\circ}
