Question Analysis

The main focus is to apply the Outside Angle Theorem for angles formed by two tangents from an external point to a circle. We need to set up an equation using the given angle and the measure of the intercepted arc to solve for .

 

Key Concept Explanation

Outside Angle Theorem for Two Tangents: When two tangents are drawn from an external point to a circle, the measure of the angle formed is half the difference of the measures of the intercepted arcs. The sum of the measures of the major and minor intercepted arcs is . If the angle is , the major arc is , and the minor arc is , then , where , so .

 

Step - by - Step Solution

1. Apply the Outside Angle Theorem:

Let the minor arc , then the major arc .

According to the theorem,
