We are going to need an image for this one.
There is no image for it
An eleven sided polygon is a hendecagon. The interior angle of a hendecagon is 147.27. If that is the interior angle, then what must be the exterior angle?
Hmmmmm, you got me in a box here
Well, how do you solve for interior and exterior angles?
Interior, add up to 180
So if you know the interior...
Welp, its exterior so I guess we subtract?
Here is the rule: An interior angle plus it's exterior angle equals 180 degrees (or a straight line) \[InteriorAngle + ExteriorAngle = 180\]
Okie
So how do I determine this?
I mean there's no image so unfortunately I have to try something different
No...if you know the interior angle, then that means there is only one unknown in our equation. The exterior angle, which is what our problem is asking for.
So I subtract 147.27 from 180?
Yes
360/11?
What did you get for a decimal? As this is what the question is asking for.
32.7
There you go
Ohhhh XD
