Ans 1:

Admin from SOF, Noida
Class : Class 10
Answer: C

Solution
If a polygon has 'n' sides, then it is divided into (n – 2) triangles. The sum of the angles of a triangle = 180°. Therefore, the sum of interior angles of a polygon having n sides is (n – 2) x 180.
(n - 2) x180 = 1440
n - 2 = 1440/180 = 8
n = 8 + 2 = 10

Ans 2:

Bindeshwari Prasad from ,
Class : Class 8
it would be 10. [n-2]180=1440 180n-360=1440 180n=1800 n=1800/180 = 10

Ans 3:

sanjay shete from ,
Class : Class 8
the answer should be 10 because= (n-2)*180=1440
