Geometry

Question Analysis:
This question tests your understanding of how interior and exterior angles are supplementary.
The main focus is on calculating the exterior angle from a known interior angle using subtraction.

Key Concept Explanation:
At any vertex of a polygon:
Interior angle + Exterior angle = 180°

Step-by-Step Solution:
Given: Interior angle = 150°
Exterior angle = 180° – 150° = 30°

Common Mistakes:
Confusing the sum of interior...
