Question

help me please

Answer 1

external angle = (360/31)° = 11.6129°

internal angle = (180 - 11.6129) = 168.3871°

Answer 8

You need to remember that the number of triangles you can create from a polygon is two less than the number of sides. Therefore, a 31 sided polygon would contain 29 triangles which means the sum of the interior angles would be 29 times 180 which equals 5220 degrees. If there are 31 sides there are 31 interior angles therefore each angle = 168.387 degrees.

26. S = 180 (n-2) 180 times 39 = 7020

27 17 times 180 = 3060
