Question

find the number of sides of a regular polygon whose each exterior angle has a measure of 45 degrees

Answer 1

Total measure of ext. angles=360
Measure of each=45

NO. of sides=360/45=8

Therefore,the answer is 8

Answer 2

Answer:

8

Step-by-step explanation:

Given : A regular polygon whose each exterior angle has a measure of 45 degrees

To Find : Find the number of sides of a regular polygon

Solution :

A regular polygon whose each exterior angle has a measure of 45 degrees

Let n be the no. of sides

So, $\frac{360}{n}=45$

$\frac{360}{45}=n$

$8=n$

Hence  the number of sides of a regular polygon are 8
