GCSE Secondary Maths Age 13-17 - Algebra: Angles - Explained

The video tutorial explains how to find the value of X in a diagram with marked angles. It begins by introducing the diagram and the concept of angles around a point summing to 360 degrees. The instructor sets up an equation involving 2X, 3X, and a right angle of 90 degrees, which equals 360 degrees. The tutorial then demonstrates solving the equation by isolating X, resulting in X being 54 degrees. The video concludes by emphasizing the importance of verifying the solution and understanding the marks awarded for each step.
