Answer:
<em>The polygon has 15 sides</em>
Step-by-step explanation:
<u>Angles in a Regular Polygon</u>
A polygon with n sides has a total sum of internal angles equal to 180°(n-2). This means that in a regular polygon, each angle measures

The regular polygon's interior angle is 156°, thus

Multiply by n:

Reducing:

Solving:

The polygon has 15 sides
