Answer:

Questioner has mentioned that a polygon has interior angles of

162

o

. It is assumed from this that all interior angles are

162

o

.

As interior angles are

162

o

, each exterior angle is

180

o

−

162

o

=

18

o

.

Sum of all the exterior angles of a polygon is always

360

o

and as each exterior angle is

18

o

,

Number of angles / sides of polygon are

360

o

18

o

=

20
