How to remember the angles of the unit circle of the angles in degrees

The video tutorial explains how to calculate angles on a unit circle. It starts by introducing the basic angles of 30, 45, 60, and 90 degrees. The instructor then explains how angles increase by 30 degrees in each quadrant and by 15 degrees between specific angles. The tutorial provides a step-by-step guide to calculating angles in each quadrant, eventually completing the circle with a full 360 degrees.

What angle do you get when you add 30 degrees to 180 degrees?

What is the final angle reached after adding 30 degrees to 330 degrees?
