Answer:
The measure of the sum of interior angles of a 11-gon is .
Each interior angle is approximately .
Step-by-step explanation:
A convex polygon has the measure of each interior angles to be less than .
But,
sum of interior angles of polygon = (n - 2) x
where n is the number of sides of the polygon.
For a convex 11-gon, we have;
sum of angles of a 11-gon = (11 - 2) x
= 9 x
=
Sum of angles of a 11-gon =
To check: convex polygons' interior angles are less than .
so that,
each interior angle of 11-gon =
=
