Using an equation to model part and whole of an angle - Free Math Videos - Online Tutor

The video tutorial explains how to solve an angle problem by first using numerical values and then transitioning to algebraic expressions. The teacher demonstrates the process of finding the measure of an angle by subtracting known parts from the whole, first with numbers and then with expressions, highlighting the use of algebraic manipulation.
