find the number diagonals of a regular polygon if the sum of interior angles is 144. Please help me, I'm a little confused.

Question

I think you are missing a zero off the angle sum...is it 1440... and not 144

No, I checked. The book says 144 degrees. I tried solving it but something's wrong. I have the right answer but I can't seem to get there.

well I think is may be a typo. there are 2 options.... 1 interior angle is 144... 

or the angle sum is 1440 so something like that... the 1st polygon is a triangle with an angle sum of 180.... 

so I'd say a typo of some sort... and this may explain the difficulty. 

good luck
