GCSE Secondary Maths Age 13-17 - Geometry & Measures: Interior Angles of Regular Shapes - Explained

The video tutorial explains how to find the size of an angle marked X in a diagram featuring a regular octagon and hexagon. It covers calculating the interior angles of these shapes and using the fact that angles around a point sum to 360 degrees to solve for X. The tutorial emphasizes the importance of understanding interior angles of regular shapes and provides a step-by-step solution, including a marking scheme for the problem.

Explain the relationship between the angles around a point and the calculation of angle X.

If the interior angle of a regular hexagon is 120 degrees, what is the value of angle X in the given problem?
