Question

What is the sum of all interior angles of a 28-sided regular polygon

Answer 1

• 4680°

====================

The sum of all interior angles of a regular polygon is calculated by the formula:

• S = (n - 2) × 180°, where n is the number of sides of a polygon

Substitute 28 for n and calculate:

• S = (28 - 2) × 180°
• S = 26 × 180°
• S = 4680°
