Based on the popular textbook by A.P. Ershova and V.V. Goloborodko, page 167 typically contains problems from Self-study Work S-13 (or the end of S-12), which focuses on the properties of Central and Inscribed Angles in a circle.

is on the major arc, the inscribed angle subtends the minor arc ACcap A cap C . The calculation above is correct for this configuration. Educational Visualization

According to the theorem on inscribed angles, an inscribed angle is equal to half of the central angle that subtends the same arc.
