Question

How many sides of a regular polygon with interior angle 177?

Answer 1

Answer:

120 sides

Step-by-step explanation:

first we have to subtract 177 from 180(linear pair..outer n inner angles)

we know sum of the outer angles always 360..

180-177=3

360÷3=120

120-2×180/120=177

inner angle 177°

so it will have 120 sides
