Whats up Kevin?

Answer 13

It's hexagon. Hexagon has 4 triangles in it. That's mean angle sum is 4*(180) = 720
135+62+151+140+n+(n+6)=720
n = 113 degree

I mean like in pentagons or octagons or a different shape, how do you know how many triangles are there?

Answer 18

You can draw it.. I mean using the same way as I draw triangles in hexagon

Answer 19

Or the quick way is using formula :
number of triangles = number of vertices - 2
