Your welcome!!!!!!!!!!!!
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°
</span>Hope this explains it.
So for a hexagon, the sum of all interior angles is 720°, all we need to do is add all the angles up and set it to 720 to get angle B.
Firstly, combine like terms to get 
Next, subtract 612 on each side, and your answer should be
