An angle with its vertex at the center of a circle intercepts an 80° arc of that circle.
What is the measure of the angle?

Respuesta :

let's recall that, arc's angle measures come from the central angle they're in.

if this intercepted arc is 80°, and is intercepted by an angle stemming from the center, namely a central angle, then the angle is also 80°.  Check the picture below.
