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.

Interior? Exterior? Interior= 180 x (n-2) when 'n' is the number of sides so for a 5 sided shape it is 180 x 3 = 540 degrees. 540=all the angles together 540 divided by the number of sides/angles is 108 Exterior= 360 divided the number of sides/angles (360 divided by 5) = 72 The total agle is 360 degrees but ech exterior agle is 72 degrees
n/18 = -72 we can solve for n by multiplying both sides by 18 which shows n = (-72)(18) = -1296
n = 19
