• A. an integral value
• B. rational value
• C. irrational value
• D. can’t be determined

Answer 1

The correct option is A

an integral value

The sum of all interior angles of a polygon is equal to (n – 2)180° where n represents the number of sides of a polygon. The number of sides of a polygon is an integral value. Hence, (n – 2)180° is an integral value.
