PLS HELP NOW

Hello There! So your question says you first have to find the the angles of all the triangles , then find there sum ( add them) then do the same for the quadrilaterals, then the hexagons, pentagons and octagons, they are asking if all of them have the same answer or not! Now you need to construct a shape using that sum. And you have to write down the function machine, the number of sides you calculated and number of angles! And then explain that do you think that it is correct!
