Question

What is the sum of interior angles of a polygon with 10 sides?

• A. 1440°
• B. 1620°
• C. 1800°
• D. 1260°

Hint:

Use the formula (n - 2) × 180° to find the sum of interior angles of a polygon with n sides.

Answer 1

The Correct Option is A

Sum of interior angles = (n - 2) × 180° 
                                     = (10 - 2) × 180° = 1440°. 
Thus, the correct answer is: \[ \boxed{\text{1440°}} \]
