Find The Measure Of The Interior Angle Of A Regular Polygon With 9 Sides. If the polygon is regular - all its interior angles are equal - you can use. Sum of interior angles p - 2 180.
540 5 108 There are 108 in each interior angle of a regular pentagon. Interior angles of a Regular Polygon 180n 360 n. Hence in a polygon with s sides or angles the sum of all the interior and exterior angles would be 180s.
Each exterior angle of a regular polygon of 9 sides n360o where n 9 9360o o 40o.
The number of sides is equal to 10. By Polygon Interior Angles Theorem we have n - 2 180 n 140 Multiply each side by n. Find the angle measure x in the following figures. A The sum of interior angles of a quadrilateral.
