The arc measure of an angle is the measure of an angle expressed as the ratio of the length of the circular arc subtended by that angle to the length of the circle's radius. The unit for an angle written this way is the radian. Proficient use of the arc measure of an angle is particularly useful when solving problems involving trigonometric functions. In two videos, Karolina will explain how to tackle this problem.
