Question

Find the number of all interior angles of the following regular polygon

1. polygon of 11 sides ​​

Answer 1

Answer:

n=11

sum of all interior angle =(n-2)×180

=(11-2)×18

=9×180

therefore sum of all interior angles of 11 sided polygon=1620

I hope this answer is helpfull :)

Answer 2

Question:-

Find the number of all interior angles of a regular polygon of 11 sides.

Solution:-

As we know the Formula to find each interior angle is (n-2)×180

(Here n denotes the number of sides given)

Now ATQ we have:-

$: \sf \purple\longmapsto{(n - 2) \times 180 \degree}$

$: \sf \purple\longmapsto{(11 - 2) \times 180 \degree}$

$: \sf \purple\longmapsto{9 \times 180 \degree} = 1620 \degree$

${\boxed { \purple{\sf{ \therefore \: 1620 \degree \: answer}}}}$
