Using an inscribed angle to determine the measure of an arc on a circle

The video tutorial explains how to find the measure of arc MP in a circle. It begins by identifying PN as a diameter, creating a semicircle with a measure of 180 degrees. The teacher then explains how to calculate the measure of an arc when the angle is on the circle, which is double the angle's measure. Using this information, the teacher sets up an equation to solve for arc MP, resulting in a measure of 118 degrees. The tutorial emphasizes understanding the relationship between angles and arcs in a circle.
