Ответ:
16.2°
Step-by-step explanation:
polygon has 20 sides
regular polygon
How to find the sum of all interior angles in a polygon?
=> (n-2) x 180
here n means number of sides
=> (20-2) x 180
=> 18 x 18
=> 324
there are as many interior angles in a polygon as many sides it has.
and the size of each angle is the same in a regular polygon.
so => 324/20 = 16.2°- Answer
