Answer:

15 sides

Step-by-step explanation:

with regular polygons it is best to work with the exterior angles since the sum of exterior angles is 360 degrees

one exterior angle = 180 − one interior angle

∴ one ext. < = 180 − 156 = 24 degrees

no of sides = 360 /24 = 15 s i d e s

(10 + 14 + 8 + 16 + 12 + x ) /6 = 13
(60 + x) / 6 = 13
60 + x = 13 * 6
60 + x = 78
x = 78 - 60
x = 18 <=====
