Answer:
The answer is Heptagon.
Step-by-step explanation:
Given is - A polygon is broken up into 5 non-overlapping triangles.
Hence, the interior angle sum is = [tex]5\times180=900[/tex] degrees
The sum of the interior angles of a convex polygon is given by:
[tex](n-2)180[/tex] degrees.
[tex](n-2)180=900[/tex]
[tex]180n-360=900[/tex]
[tex]180n=1260[/tex]
[tex]n=7[/tex]
Hence, the number of sides the polygon will have is 7.
And 7 sided polygon is called a heptagon.
