Question

5. Find the measure of exterior angles of a regular polygon of 10 sides.
6. Each exterior angle of a regular polygon measures 20°. How many sides
does it have?​

Answer 1

Answer:

5) whatever may be the polygon

sum of exterior angles is always equals to 360

each exterior angle = 360/n

= 360/10 = 36°

6) each exterior angle = 360/n

20=360/n => n=18 sides
