The size 0f each interi0r angle (A) 0f a regular p0lyg0n can be f0und by the
f0rmula A=(n-2)x180°/n , where n is the number 0d sides 0f the p0lyg0n. If the size 0f each interi0r angle 0f a regular p0lyg0n is 172°, find the number 0f sides 0f that p0lyg0n.

✔ 最佳答案
A=172°A=(n-2)x180°/n
172 = (n-2) X 180 / n
172n = 180n - 360
8n = 360
n = 45
Number of sides is 45
