Learn to find the missing angle outside of a circle with a secant and tangent line

The video tutorial covers the calculation of angles related to circles, focusing on angles formed inside, on, and outside the circle. It explains the formulas for finding these angles, such as using half the sum of arcs for angles inside the circle and half the difference of arcs for angles outside. The tutorial also demonstrates how to calculate specific arc measures and apply these formulas to solve problems, emphasizing the importance of understanding the relationships between arcs and angles in circle geometry.
