Question

the number of sides of two regular polygons are in the ratio 4:5
and their interior angles r in the ratio 15:19 find the number of
sides of each

Amrit Lal · Answer

Let number of sides are 4x and 5x
Then (4x - 2)180 / (5x - 2)180 = 15/19
76x - 38 = 75x - 30
x = 8
Thus number of sides are 32 and 40 Answer

the number of sides of two regular polygons are in the ratio 4:5 and their interior angles r in the ratio 15:19 .find the number of sides of each..
