A nine sided shape has 7 triangles
9-2 = 7 triangles

A decagon has ten sides, a hexagon has 6, a nonagon has nine, and a triangle has three. So 2 decagons, 1 hexagon, 4 nonagons, and 2 triangles have 2*10 + 1*6 + 4*9 + 2*3 = 20 + 6 + 36 + 6 = 68 sides altogether.
There are 7 triangles in a nonegon

The smallest number of triangles that you could divide a nonagon into is seven.
It can form 7 triangles
Each decagon has 10 sides, each nonagon has 9 sides and each pentagon has 5 sides. 4 decagons make 40 sides, 2 nonagons make 18 sides and 2 pentagons make 10 sides. When you add them all up together, you get 68 sides in total.
