Points A, B, C lie on a circle with center O. The AOC angle is 146 degrees. Find the angle ABC if points B and O lie on one side of the line AC.

AOC is the center corner. The arc on which the central angle rests is equal to the degree measure of that angle. => AC minor arc = 146 degrees. The ABC angle also lies on the small arc AC and is called the inscribed angle. The inscribed angle is equal to half of the arc on which it rests: 146: 2 = 73
Answer: 73
