Are you in geometry?

anonymous · Answer

yes & it's so frustrating . I hate it .

anonymous · Answer

Its alright, I will help you. An exterior angle can exterior angle of a polygon is an angle that forms a linear pair with one of the angles of the polygon.  So we can look from here and dismiss some answers

anonymous · Answer

Think about this: the formula for the measure of an exterior angle of a regular polygon is 360/n, where n is the number of sides. So if the number you get can be put into 360 with a whole number, then you have to find the choice that doesn't go into 360 nicely.

anonymous · Answer

ok, that'd be great.

@HemerickLee

anonymous · Answer

So test the choices by dividing 360 by them.
360/45
360/36
360/40
360/54

anonymous · Answer

It is going to be the 40 degrees because it doesn't go into the answer nicely like that lady said for the formula.. Thank you @thechocoluver445

Wait. Why are we all in history or it's only me?

anonymous · Answer

Yeah, @saifoo.khan's right. This should be in the math section...
But @HemerickLee actually 40 goes into 360 9 times, so that's not it.

@HemerickLee  @thechocoluver445 thank you guys so much :)

anonymous · Answer

So it would be 54.

anonymous · Answer

Yep.

anonymous · Answer

54

anonymous · Answer

I divided the wrong way..... Oooops...

anonymous · Answer

we all make mistakes :)

SAIFOO?!?!?!?!?

anonymous · Answer

No problem, @HemerickLee  :)

saifoo.khan · Answer

YO?! @SnuggieLad

anonymous · Answer

I'm guessing you two know each other :P
