which angle?
OpenStudy (anonymous):
thats all it says
OpenStudy (anonymous):
The polygon would have 30 sides. to work this out you subtract the interior angle from 180 then divide 360 by this number so in this example: 180-168=12 360/12=30
OpenStudy (anonymous):
Say it's the interior, then exterior is 12 and sides are 360/22
OpenStudy (anonymous):
how did u get 22
