Question

Find the number of sides in a polygon if the sum of it's interior angles is a). 900 degree​

Answer 1

Answer:

Step-by-step explanation:

Sum of interior angles= (n-2)180

(n-2)180=900

(n-2)=5

n=7

Answer 2

Answer:

The required answer is 7

Step-by-step explanation:

Let n be the number of sides in a polygon if the sum of it's interior angles is 900°

Then

2(n-2)×90°= 900°

2(n-2) = 10

(n-2) = 5

n = 7
