N=72
The sum of the exterior angles is 360. So we have 360/n= 72 or 72n=360 from which we see n=360/72=5 So it is a pentagon! Dr. Chuck
8n = 72 n = 72 / 8 n = 9
2o degreees the formula is 360 divided by n n meaning number of side so in this case 360 dividedby 18 which equals 20 360/n 360/18 20
Let n be the number of sides of the regular polygon. Given: (360 / n) = 72 Therefore, n = 360 / 72 = 5 =========================
It is the property of n as the additive identity.
90
n/18 = -72 we can solve for n by multiplying both sides by 18 which shows n = (-72)(18) = -1296
n = 19
n=24
N=20
