Answer 1

Answer:

* 12 Sides of polygon total interior Angle = (12-2) × 180

= 10 ×180

= 1800 degree

Each angle = 1800 / 12

Each angle = 150 degree

Therefore each Exterior Angle = (360 - 150) degree

Each Exterior Angle = 210 degree

Then

* 18 sides of polygon total interior angle = (18 -2) × 180

= 2880 degree

Each Angle = 2880 / 18

Each Angle = 160 degree

Therefore each exterior angle = (360 - 160) degree

Each exterior Angle = 200 degree

* QUADRILATERAL POLYGON IS A CONCAVE BECAUSE TOTAL INTERIOR ANGLES ARE GREATER

THAN 180 DEGREE...
