Question

Find the sum of interior angles of regular octagon.

Answer 1

Step-by-step explanation:

please refer above.

note oct means 8 so write 8 in n and u will find rhe answer

Answer 2

Given: Here we have given the regular octagon with 8 sides

To find: we have to find the sum of interior angles of regular octagon

Solution:

• Here we know that the interior angles of regular octagon is

• The sum of the interior angles of a polygon =(2n−4)×90 degree

       where n is the side

       Here we have the regular octagon which has 8 sides

      so, n=8

=(2×8−4)×90

=(16-4)×90

=(12)×90

=1080 degrees

So, the sum of interior angles of regular octagon is 1080 degrees
