What is the sum of the interior angles of a decagon
Answer (1)
Answer:1440°Step-by-step explanation:To get the sum of the interior angles of a polygon, we use the formula:Sum of interior angles = (n-2) x 180°where n is the number of sides of the polygon.A decagon is a 10-sided polygon. Here n=10. Using the formula:Sum of interior angles = (n-2) x 180° = (10-2) x 180° = 8 x 180° = 1440°Hence, the sum of the interior angles of a decagon is 1440°.
