Would assume the Polygon is an 18 sided regular polygon.
Exterior angle for regular polygon = 360/n (Sum of angles of exterior angles = 360°)
where n = number of sides.
Exterior angle = 360 / 18 = 20
Exterior angle = 20°
Sum of exterior angle + Interior angle = 180° (Both angles are on a straight line, so the sum is 180°)
Interior angle = 180° - 20°
Interior angle = <span>160°

11.45... to solve it, you add all of the numbers and then divide by the total number of numbers. so 126 divided by 11

Answer:
$960
Step-by-step explanation:
1/5= .2
1-0.2= 0.8
1200×0.8= 960
