Step-by-step explanation:

On counting the total number of triangles formed by the connecting vertices and the point O we get a total of 9 triangles.

On counting the total number of triangles formed by the connecting vertices and the point O we get a total of 9 triangles.We know that the sum of angles of a triangle is equal to 180∘ . Since there are 9 triangles formed in a nonagon, therefore the total angle subscribed will be 9 times 180∘. Mathematically it will be written as:
