Math Problem Statement
Find EDC
Solution
To find the measure of angle , we analyze the geometry of the given circle and the angles involved. Let’s proceed step by step:
Given:
- are points on the circumference of a circle.
- .

Step 1: Use the Inscribed Angle Theorem
- The inscribed angle subtends the same arc as (both subtend arc ).
- By the Inscribed Angle Theorem, .
Step 2: Conclude
Since , we have:
Thus, .
