Hey it's too simple dear
A class 6th level question,
A polygon with 5 sides,
It's a question of permutations and combinations
Triangle with two sides as the side of polygon = 5 taking two adjacent sides of polygon at a time
Triangle with one side as side of polygon = 5 with each of the sides of the polygon
Triangle with no side common with polygon = 0
So your answer is 5 + 5 =10
