Question

Sum of the interior angles of a polygon with 8 sides *
240°
1080°
720°
800

Answer 1

Answer:

1080

Step-by-step explanation:

Sides=8

⇒ Sum of interior angle of polygon =(2n−4)90

                                                            =(16−4)90

                                                            =12×90

                                                            =1080

Hence, the answer is 1080.

Answer 2

Answer:

The sum of the interior angles in a regular polygon is given by the formula 180(n – 2), where n is the number of sides in the polygon. An octagon has eight sides, so the sum of the angles of the octagon is 180(8 – 2) = 180(6) = 1080 degrees
