A regular polygon has an interior angle of approximately 158.8°.

Step2247 [10]

Answer:

17 sides

Step-by-step explanation:

Property of regular polygons:

Sum of Interior Angles = (n−2) × 180°, where n is number of sides

In our case we have:

158.8×n = (n - 2)×180
180n - 158.8n = 360
21.2n = 360
n = 360/21.2
n = 17
