which of following is sum of all the interior angles of a polynomial of 'n' sides is
1. (n+2)×180
2. (n-2)×180​

Answer 1

Answer:

Hey friend,

Here is the answer you are searching for,

The right formula is (n-2)180°.

Let's take an example of triangle,

Number of sides = 3

Therefore,

Sum of all interior angles in it = (3-2)180° = 180°
