are there options or is this it

anonymous · Answer

That's it

beastboy17 · Answer

okay so do you have a suspicion of what the answer could be

welshfella · Answer

the sum of the exterior angles = 360
1 exterior angle = 360 / 12 = 30 degrees
so interior angle 180 - 30

anonymous · Answer

A. 100(10-2)=200;40°
B. 360(12-2)=3600;300°
C. 90(12-2)=900;75°
D. 1800(12-2)=1800;150°

I think it could be D

beastboy17 · Answer

id probably agree but im not 100%

beastboy17 · Answer

id hate to agree and have it be incorrect

welshfella · Answer

formula for sum of all angles = 180(n - 2)
here n = 12

dividing this by 12 will give the measure of one angle

welshfella · Answer

1808 10 = 1800
1800 / 12 = ?

welshfella · Answer

* first line should read 180 * 10

welshfella · Answer

what 's 1800 divided by 12?
