A polygon of n sides has a half its interior angles equals to 150 degrees.while the rest of are equal to 170 degrees each.
Find the number of sides of the polygon
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

18-gon.

18 sides and 18 vertices.

9 angles by 150° and 9 angles by 170°.


9*150° + 9*170° = 2880°.

From the other side,  (18-2)*180° = 2880°.
