Each interior angle
WebWe know that the sum of all interior angles of a polygon of n sides is 180(n-2)° degrees. Hence, the sum of the interior angles of the pentagon is: 180 × (5-2)° =180 × (3)° = 540° Since the given pentagon is regular, … WebEach interior angle of a regular nonagon measures 140°. This can be calculated using the formula for the interior angles of a regular polygon. Interior angle of a regular polygon =\(\frac{180n–360} {n}\), where n = the number of sides of the polygon. In a nonagon, n = 9. After substituting this value of 'n' in the formula, we get \(\begin ...
