i also misread  x=((180−20)/2)=80  thanks Rashid sir for correction

i misread as octagon.  in case of octadecagon, the right answer  is indeed 80°.  ((360)/9)−((360)/(18))=20  x=((180−20)/2)=80°  Ar Brandon sir:  sorry for my mistake!

2x+5°=180°  ⇒x=((180−5)/2)=87.5°
2x+5°=180°x=18052=87.5°

interior angle =180°−exterior angle                                 =180°−((360°)/n)
interiorangle=180°exteriorangle=180°360°n

Right answer is 80° , sir ��
Commented by mr W last updated on 27/Sep/22
87.5° is correct!  ((360)/8)−((360)/9)=5  x=((180−5)/2)=87.5°
87.5°iscorrect!36083609=5x=18052=87.5°

OK sir. If you both agree on that. Thanks!

this is not an opinion, but a fact!  it is proved that x is and can only be  87.5°.
