The document contains notes from a math lesson. It includes an assignment that is due the next day, five warmup problems simplifying expressions and solving equations, and information about central angles and arcs. Examples are provided to demonstrate finding the measure of central angles and arcs based on a fraction of the total circumference. The lesson covers central angles, minor and major arcs, and includes examples to work through.
