Answer:
24 sides
Step-by-step explanation:
exterior angle + interior angle = 180°
exterior angle + 165° = 180° ( subtract 165° from both sides )
exterior angle = 15°
the sum of the exterior angles of a polygon = 360°
since the polygon is regular each of the exterior angles are congruent
number of sides = 360° ÷ 15° = 24
