Answer
Triangle = 60° ; Quadrilateral = 90° ; Pentagon = 108° ; Octagon = 135° ;
Decagon = 144° ; 30 -gon = 168° ; 50 -gon = 172.8° ; 100 -gon =176.4°
Step-by-step explanation:
You follow the equation (N-2)*180, then divide the answer with the the number of sides. Example for Triangle: (N-2)*180=(3-2)*180=(1)*180=180 then divide by 3 because in a triangle there are 3 sides. 180/3=60.
