Vertically Opposite and Supplementary Angles

The video tutorial explains how to find unknown angles using the properties of vertically opposite angles and the sum of angles on a straight line. It demonstrates that angle X is vertically opposite to angle BC, which is 33 degrees, making angle X also 33 degrees. It further explores angles on straight lines, showing that angle PR is 50 degrees, and calculates angle W as 130 degrees using the sum of angles on a straight line. Finally, it concludes that angle Y, being vertically opposite to angle W, is also 130 degrees, summarizing the unknown angles as 50, 130, and 130 degrees.
