Question

find the sum of interior angles of a 11 sided polygon and also find its number of diagonals

Answer 1

Answer:

1620°

44 diagonals

Step-by-step explanation:

formula for finding sum interior angles is

=>(n-2) * 180

=> n= 11

=> (11 - 2) * 180

=> 9 * 180 = 1620

formula for no of diagonals is

=> n(n - 3)/2

=> n = 11

=> 11(11 - 3)/2

=> 11 * 8 / 2

=> 88 / 2 = 44
