Question

If each interior angle of a regular polygon is 144°. Find the number of sides and hence the number of polygons.​

Answer 1

Answer:

10

Step-by-step explanation:

A regular polygon has an interior angle of 144 degree, calculate the number of sides polygon has. Since the interior angle is 144 degree, each exterior angle is 180 - 144 = 36 degrees. For any convex polygon (in particularly, for any regular polygon) the sum of exterior angles is 360 degrees. = 10.
