Question

for each of the regular polygons in question 2, find the size of the exterior angle​

Answer 1

Answer:

Step-by-step explanation:

We know that the measure of exterior angle is (  

n

360

​  

)  

∘

 where n is the number of sides of the regular polygon.

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

(  

n

360

​  

)  

∘

 

​  

 

=(  

20

360

​  

)  

∘

 

=18  

∘

 

​  

 

Hence, the measure of each exterior angle is 18
