The video tutorial explains how to find the value of x in two different circle diagrams. It begins by introducing the problem and identifying the location of x. The instructor explains that the sum of central angles in a circle is 360 degrees. In the first shape, x is calculated by subtracting the sum of given angles from 360 degrees, resulting in x being 50 degrees. In the second shape, a similar method is used, and x is found to be 145 degrees.
