Question

sum of the angle in regular polygon with 5 sides​

Answer 1

Answer:

540 degrees

Step-by-step explanation:

A regular polygon with 5 sides is a regular pentagon

it contain 3 triangles with the angles on edges

the total sum of interior angles of a triangle = 180 degrees

so the sum of interior angles of three triangles =180*3 =540degrees

the sum of angles in a regular polynomial with 5 sides is 540 degrees
