Question

is it possible to have a polygon whose sum of interior angle is 1120⁰​

Answer 1

Answer:

Let no. of sides =n

Sum of angles =870o

(n−2)×180o=870o

n−2=180870

n−2=620

n=629+2

n=641

Which is not a whole number.

Hence, it is not possible to have a polygon, the sum of those interior angles is 870o
