Answer:
Step-by-step explanation:
As we know that
In any convex polygon, if we may start at one vertex and draw the diagonals to all the other vertices, we would form triangles,
The number of triangles thus formed would always 2 LESS than the number of sides.
As
Thus,
The sum of the interior angles of the 15-gon will be:
[tex]13\:\times\:180\:=\:2340^0[/tex]
Also
15-gon is regular, it means this total [tex]2340^0[/tex] is shared in equal proportion among the 15 interior angles.
And
Each interior angle of the regular polygon will be: [tex]\frac{2340^{0} }{15}=156^{0}[/tex]
Therefore, we conclude that:
