Find the inscribed and center angles if they rest on a 125 ° arc

The degree measure of the central angle is equal to the degree measure of the circular arc on which it rests: ∠AOB = ∪AB. By condition ∪AB = 125 ° → ∠AOB = 125 °.

The inscribed angle is equal to half the degree measure of the arc on which it rests: ∠ACB = 1 / 2∪AB. By the condition ∪AB = 125 ° → ∠AСB = 1/2 * 125 ° = 62.5 °.
