GCSE Secondary Maths Age 13-17 - Shapes & Area: Algebra - Explained

The video tutorial explains how to find the size of angle X in a diagram featuring a regular octagon and hexagon. It covers calculating the interior angles of these polygons and using the fact that angles around a point sum to 360 degrees to solve for X. The tutorial also discusses the marking scheme for the problem, emphasizing the importance of understanding interior angles of regular shapes.

What is the relationship between the angles around a point and the calculation of angle X?

Explain how to determine the angle marked X in the diagram.
