Question

Find the measure of an interior and an exterior angle of a regular 46-gon

Answer 1

Sum of interior angles =
(n−2)∗180/n

n is 46-gon
You want to measure the 46-gon interior angles
So
= (46 - 2) * 180 / 46
(46 - 2) * 180 =7920 degrees
Divide the interior measure 7920 by the n-gon which is 46
7920/46=172
-----------------------------
As for the exterior angles measure
The sum of the exterior angles is
360/n
And n=46
So
360/46=7.8 close to 8
