Mikaela drew a regular polygon and measured its interior angle as 160°. Is it possible? If so, how many sides does the regular polygon have?

A. Yes, it's possible. It is a 20-gon.
B. No, because the number of sides of a polygon cannot be a decimal number. 360/160 = 2.25
C. No, because it's impossible for a regular polygon to have very large measure as 160^ .
D. Yes, it is possible. The regular polygon has 18 sides.​
