Correct Answer
Option C
Explanation
To determine why Option 3 is the correct answer, let's analyze the given information and apply geometric principles. ### Given: - ∠BAD = 125° - ∠EBC = 100° ### Analysis: 1. Understanding the Angles: - Since AB is produced to E, ∠BAD is an exterior angle for ∆ABC at vertex A. - Similarly, since CA is produced to D, ∠EBC is an exterior angle for ∆ABC at vertex B. 2.…Read More
