What is the measure of each exterior angle in a regular 10-sided polygon?

Question

habbster · Answer

what is the sum of all the angle inside the polygon?

anonymous · Answer

doesn't give it.. But I'm guessing it'd be 360, right?

habbster · Answer

(n-2) × 180° where n is the number of sides

anonymous · Answer

Ah, I should remember that.. I just did this. Alright thanks for reminding me though. haha... ah..

anonymous · Answer

oh wait

anonymous · Answer

But when It says to give a numerical answer only, what would I put? because I've gotten a fraction before and it came out as wrong..

habbster · Answer

no it should be (10 - 2)x 180
so the sum of the interior angles is 1440

anonymous · Answer

oh okay..so if it was 12-2*180, it would have just been1800?

habbster · Answer

yes

anonymous · Answer

alright thank you

habbster · Answer

since the polygon is 10 sides divide the sum by 10 so one interior angle is 144

anonymous · Answer

What if that isn't an option..?

habbster · Answer

what do you mean?

anonymous · Answer

well it's multiple choice and 144 isn't one of them it has 
360
18
180
36

habbster · Answer

no, that was not the answer yet :D

anonymous · Answer

oh haha silly me

habbster · Answer

after getting the 144
since the angle of a straight line is 180 
to find the exterior angle you need to subtract 144 from 180

anonymous · Answer

oh okay so 36?
