Question

What is the measure of one angle of a regular 16-gon? If necessary, round to the nearest degree
a) 120
b) 135
c) 140
d) 158

Answer 1

hint : find exterior angle

Answer 2

which is 180(n-2) ?

Answer 3

360(n-2) ?

Answer 4

find the angle sum

(n - 2) x 180 n = number of sides

when you know the angle sum divide it by 16... as there are 16 angles


the alternate method is that the exterior angles of a polygon = 360

360/16 gives the size of 1 exterior angle.

just find the supplementary angle to get the interior angle size

Answer 5

got it, D
