If each exterior angle is 9 degrees then it is a regular 40 sided polygon.
15 degrees
360/9 = 40 degrees
6 degrees if it's a regular polygon
Recall that the measurement of interior angle is: 180°(n - 2)/n Given that a regular polygon has 6 sides, let n = 6. Then: 180°(6 - 2) / 6 = 180° * 4 / 6 = 120° Since the total measurement of interior and exterior angles is 180°, 180° - 120° = 60°, which is the measurement of the exterior angle of the regular polygon.
The angle is 72 degrees.
Assuming I understand your question, the exterior angle of a regular pentagon is 72 degrees
If each exterior angle is 9 degrees then it is a regular 40 sided polygon.
15 degrees
360/9 = 40 degrees
Each exterior angle 36 degrees Each interior angle 144 degrees A decagon has 10 sides
36 degrees
6 degrees if it's a regular polygon
360/5 = 72 degrees
Recall that the measurement of interior angle is: 180°(n - 2)/n Given that a regular polygon has 6 sides, let n = 6. Then: 180°(6 - 2) / 6 = 180° * 4 / 6 = 120° Since the total measurement of interior and exterior angles is 180°, 180° - 120° = 60°, which is the measurement of the exterior angle of the regular polygon.
Providing it is a regular nonagon: Exterior angle: 40 degrees Interior angle: 140 degrees
Interior angle+exterior angle = 180 degrees
