Please someone I need help please answer me​

Answer 1

Answer:

540°

Step-by-step explanation:

Given that formula to calculate sum of interior angle of a regular pentagon

s = (n-2) * 180

where n is number of side of a polygon which in this case is 5 because pentagon have 5 sides

s =(5-2) * 180

s =(3)* 180

s =540°

A pentagon has 5 sides, and can be made from three triangles, so you know what its interior angles add up to 3 × 180° = 540°

Hope it helps you.
