Answer: 360°
Explanation:
The sum of the exterior angle of a polygon is always 360°
Or, From the sum of the interior angle of a polygon,
(2n - 4)× 90° where n = 8
(2 × 8 - 4) × 90 =
16 - 4 × 90
12 × 90 = 1080°
Now each interior angles of the polygon
= 1080/8
= 135°.
Now, to find each exterior angle of the polygon,
= 180°- 135°
= 45°
To find the exterior angle now, we multiply 45° by eight
= 45° × 8
= 360°
