Answer:
3.6° = ext. angle
Step-by-step explanation:
For the shape to be a regular polygon, all interior angles must be congruent.
We can find every interior angle by using the formula:




176.4 = each int. angle
We also know that int. and ext. angles are supplementary!
180 = 176.4 - x
3.6° = ext. angle
The answer is y= -6
my apologies if it’s wrong
I hope this helps you
Perimeter =2 (width +length )
324=2 (67+length )
162-67=length
length =95
The answer to that equation is X= -1
