C step-by-step the coordinate of that is pretty simple to say but hard at the same time
Measure of sum of interior angles formula (where “n” is number of sides): (n-2)180
(21-2)180
=3420
3420 is the measure of the sum of a regular 21-gon, and to find the measure of only one angle, we need to divide the sum by the number of sides, so
3420/21
= 162.9
the answer is B
