Triangle Properties and Angle Relationships

The video tutorial explains how to find the angle x in a geometric problem involving triangles. It begins with setting up the problem and identifying key angles and sides. The tutorial covers the exterior angle theorem, straight angle property, and properties of isosceles and equilateral triangles. Through step-by-step analysis, the video demonstrates how to calculate various angles and concludes with finding the value of angle x as 30 degrees.
