What is the exterior angle of an 20 sided shape?
If it's regular then 360/20 = 18 degrees
What is the sum of the interior angle measured by a 20-sided polygon?
162o. Method 1: Sum of interior angles of n-sided polygon = (2n - 4) right angles. In this case n = 20 so total of interior angles is 36 x 90o. Assuming polygon is regular then each interior angle is (36 x 90) divided by 20 = 3240/20 = 162. Method 2: Exterior angles of regular n-sided polygon = 360/n which in this case = 360/20 =18. Straight line is 180o so interior angle = (180 - exterior angle) = 180 - 18 = 162.
What is the interior and exterior angles on a 20 sided shape?
Interior angles total 40 - 4 right angles, ie 36 x 90o, so each interior angle is 18 x 9 ie 162o and the exterior is 180 - 162 = 18o
What are the interior angles of a 20 sided polygon?
If the 20-sided polygon is a regular polygon, then:The sum of all 20 angles = (20 - 2)180⁰ = 18(180⁰) = 3240⁰Each angle measure = 3240⁰/20 = 162⁰
What is the measure of each interior angle of a twenty side polygon?
Interior angle of any n-sided polygon = (2n - 4) x 90/n degrees in this case n = 20 so you have 36 x 90/20 = 162o
