Explanation of Solution
Given:
The figure is an octagon.
Calculation:
According to the Polygon Interior Angles Sum Theorem, the sum of the measures of interior angles of an n-sided convex polygon is
There are 8 sides in an octagon.
Therefore;
Make all the diagonals in an octagon from one vertex.
From the figure above, it can be seen that the octagon is split into 6
The sum of the measures of interior angles in a triangle is 180.
According to Angle Addition Postulate, the sum of the interior angle measures will be:
