Question

Find the measure of each interior and exterior angle of the following regular polygons 17) A regular nonagon 18) a polygon with 12 sides​

Answer 1

Answer:

30°

Step-by-step explanation:

We know that, the measure of each exterior angle for an n-sided regular polygon is (360/n)°

Here, it is given that the number of sides n=12.

∴ (360/n)° =(360/12)°=30°

Hence, the measure of each exterior angle of a regular polygon with 12 sides is 30°

Answer 2

REGULAR NONAGON

interior angle = 140 deg each

exterior angle = 40 deg each

POLYGON WITH 12 SIDES

interior angle = 150 deg each

exterior angle = 30 deg each
