Question

find the number of a regular polygon if the ratio of each interior and exterior angle is 3 : 2​

Answer 1

Step-by-step explanation:

Hence exterior angle is 20*2 = 40 degrees and the interior angle 20*7 = 140. The number of sides of the regular polygon = 360/40 or 9 sides. Check: A nonagon has 9 sides. Sum of the interior angles = (2n-4)*90 = (18–4)*90 = 14*90 = 1260 degrees.

Answer 2

answer

extererior angle of regular polygon is 180

so,let the no be x

3x+2x=5x

5x=180

x=180/5=36
