Question Analysis

The main focus is on correctly applying the Tangent - chord theorem. We are given the angle between the tangent and the chord , and we need to find the measure of the intercepted arc, which in this case is the major arc .

 

Key Concept Explanation

Tangent - chord Theorem: The measure of the angle formed by a tangent and a chord is equal to half the measure of the intercepted arc. Mathematically, if is the angle between the tangent and the chord, and is the measure of the intercepted arc, then .

 

Step - by - Step Solution

1. We are given that the angle between the tangent and the chord is .

2. According to the Tangent - chord theorem, to find the measure of the intercepted arc (major arc
