To solve the problem step by step, we will follow the reasoning presented in the video transcript. ### Step 1: Understand the Given Information We have a circle with center O, and two tangents PA and PB drawn from an external point P. The angle between these tangents, ∠APB, is given as 80 degrees. ### Step 2: Identify Important Angles Since PA is a tangent to the circle at point A, the radius OA is perpendicular to the tangent PA. Therefore, we have: \[ ...
