Question

6. Find the number of sides of a regular polygon, when each of its angles
has a measure of 160 degree plx answer fast

Answer 1

Answer:

18 sides.

Step-by-step explanation:

If the interior angle of a regular polygon is 160 degrees, then the exterior angle is 20 degrees. The sum of all exterior angles is 360 degrees so there must be 360/20 sides = 18 sides.

Answer 2

Answer:

18 sides

As,

Formula for total number of angles inside a polygon:- (n-2)*180 degrees

So, it becomes  

180n - 360 = n*160 = 160n

180n - 160n = 360

20n = 360

n= 360 /20= 18

Therefore, There are 18 sides
