Answer 1

Step-by-step explanation:

Formula=(n-2)×180

if n=7

so,(7-2)×180

5×180

=900

Answer 2

Given:

There are 7 sides of a convex polygon.

To Find:

The angle sum of a convex polygon with number of sides 7.

Solution:

We know that,

If a convex polygon has n sides, then its interior angle sum is given by the following equation:

S = ( n −2) × 180°

Here, we have n = 7

So, by substituting n = 7 in the equation, we get

S = ( 7 −2) × 180° = 5 × 180° = 900°

Hence, the angle sum of a convex polygon with number of sides 7 is 900° (option a).
