Question

find the number of sides of a regular polygon of each exterior angle
i 20
ii 12​

Answer 1

Step-by-step explanation:

We know that the measure of exterior angle is(n360 ) 0 where n is the number of sides.

Here, it is given that the number of sides n=20, therefore,

( n360 ) 0 =( 20 360 ) 0

=18 0

Hence, the measure of exterior angle is 18 0 .

Originally Answered: How many sides does a regular polygon has if each of its exterior angle is 12°? The formula for exterior angle in 360/n. So if 360/n = 12, that means n = 30. So, the regular polygon has 30 sides.
