Question

What’s the sun of the interior angle measures for convex nonagon.

Answer 1

We need to find the sum of the interior angles of a convex nonagon.

First, let's remember that a nonagon is a polygon with 9 sides.

Also, the formula to find the sum of the interior angles for a convex polygon of n sides is:

$\text{ sum of interior angles }=(n-2)\cdot180\degree$

So, in this case, we have n = 9. Using this value in the above formula, we obtain:

$\begin{gathered} \text{ sum of interior angles of a convex nonagon }=(9-2)\cdot180\degree \\ \\ =7\cdot180\degree \\ \\ =1260\degree \end{gathered}$

Therefore, the answer is 1260º.
