Sum of interior angles regular polygons = (n−2)×180
sides of two regular polygons= x and y
So, x/y=3/4
x=3y/4
Sum of interior angles regular polygons (x)=(x−2)×180
Sum of interior angles regular polygons (y)=(y−2)×180
(x−2)×180/(y−2)×180=2/3
x−2/y−2=2/3
3y/4−2/y−2=2/3
3y−8/y−2=8/3
9y−24=8y−16
y=8
x=3y/4=3×8/4=6
Answer (1) 6 and 8, (2) 8 and 6.
