Answer options

  1. 30
  2. 40
  3. 45
  4. 36

Correct answer and explanation

Correct answer: 40

Explanation: āœ… Correct Answer: B. 40 šŸ“š Explanation: For any regular polygon, the sum of all exterior angles is always 360 degrees. To find the number of sides, we divide 360 by the measure of one exterior angle. Calculation: 360 / 9 = 40. Therefore, a regular polygon with 9-degree exterior angles has 40 sides. This is a fundamental property of geometry.
