Answer:
24
Step-by-step explanation:
Let number of sides of given regular polygon is n.
Then, sum of all of the angles can be given as,
S=(n−2) x 180∘.... (1)
Also, as we are given each interior angle is 165∘,
So, Sum of all the angles will also be,
S=165n.... (2)
From (1) and (2),
(n−2) x 180=165n
180n−360=165n
⇒15n=360
⇒n=360/15
⇒n=24
So, number of sides in the given polygon is 24.
