Finding the length of a segment given the whole and part - Free Math Help - Online Tutor

The video tutorial explains how to find the length of a line segment when given the total length and a part of it. It introduces points A, B, and C, with known lengths from B to C and the total length from A to C. The tutorial demonstrates how to calculate the missing length AB by subtracting the known part BC from the total length AC. The key concept is understanding how to find a missing part when given a whole and another part.

If the length of AB is unknown, how can you express it in terms of AC and BC?
