Question 217754
Remember  the  formula  for  the sum  of  the  interior  angles  of  a  polygon is
.
(n-2) * 180,,,,,,,,,,,,,,for  a  triangle  with  3  sides,,,,(3-2)(180)=180,,,,ok
.
however  the  individual  angles  is  the  sum  / n,,,,,,or
.
(n-2(180)/n
.
applying  this  to  174
.
(n-2)(180)/n = 174
.
(n-2)(180) = 174 n
.
180n -360 =174n
.
6n = 360
.
n=60,,,,,,answer
.
.
check,,,(n-2) (180) /n = 58 *180 / 60 = 174,,,,ok
.
