Sum of measures of all angles of a triangle =(n-2)×180°

So sum of all angles of a regular pentagon with n=5sides =(5-2)×180

3×180=540° Each angle measure =sum of all angles/ no of sides= 540/5=108°

Answer 108°

Hope it helped you

Pentagon is a polygon with 5 sides.

Sum of exterior angle of any polygon is 360 degree

For any polygon with N sides exterior angle =360/N

=360/5

=72 degree

Pentagon has 5 exterior angle and each one is 72 degree
