180 degrees - 160 degrees = 20 degrees (the exterior angle). 360/20 = 18sides
There's no state there. That point is in the Pacific Ocean,about 125 miles south of the nearest point of Hawaii.

20 degrees
180 - angle = supplement 180- 160 = 20 degrees
It is: 160 degrees
160 degrees or one hundred and sixty degrees
160 The 2 angles must equal 180 degrees, so 160 is the answer.
The state of argon at 20 degrees is a gas.
Its exterior angle is 20 degrees and it will have 360/20 = 18 sides
