A= (a+b+c)h is the formula. I hope this is helpful for you. I am pretty positive it will help.
1. sum of exterior angles = 360
so one interior angles = 180 - (360/30) = 180 - 12 = 168 degrees
sum of all the interior angles = 168*30 = 5040
B
2. H
the sum of exterior angles of all polygons is 360 degrres
The coefficient is 2, the first number being multiplied by a variable will always be the coefficient.
