The video tutorial explains how to find the measures of angles x, y, and w using the properties of triangles. It demonstrates that the sum of the interior angles of a triangle is 180 degrees. The tutorial walks through the process of calculating each angle by subtracting the known angles from 180 degrees. Angle Y is calculated as 48 degrees, angle W as 38 degrees, and angle X as 105 degrees. The video concludes with a summary of these calculations.
