Answer:

  18

Step-by-step explanation:

Each exterior angle is the supplement of the adjacent interior angle, so is ...

  180° -160° = 20°

The total of all n of these exterior angles is 360°, so we have ...

  n(20°) = 360°

  n = 18 . . . . . . . . . divide by 20°

The polygon is an 18-gon. It has 18 sides.

Answer:

18 Sides

Step-by-step explanation:

Each interior angle = 160°

Each exterior angle = 180° - 160° = 20°

The sum of the exterior angles = 360°

Hence the number of exterior angles =360°/20°

= 18

The polygon has 18 sides (since it has 18 exterior angles).
