The measure of each interior angle of a regular polygon is 172. find the number of sides in the polygon.

45.

Step-by-step explanation:

Each exterior angle = 180 - 172 = 8 degrees.

Since the total of the exterior angles = 360 the number of sides =

360 / 8

= 45 sides.

NOTE: the  total of exterior angles of all polygons = 360 degrees.

x + 4/7

step-by-step explanation:

use cymath

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
