Question

5. If an exterior angle of a regular polygon is 45°, then find the number of its sides.

Answer 1

we know that Each exterior angle of a n -sided regular polygon is 360/n

Given Each exterior angle =45

So 45=360/n

n =360/45

n=8

Hence number of sides of a polygon whose one exterior angle is 45° is 8 sides

Answer 2

hi
here is ur ans



Exterior angle of a regular polygon = 360/n
so here n = 45
:-
360/45
=8
so no.of sides = 8 sides
hope it helps uh
