In the isosceles triangle below, the congruent sides each measure 13 meters. if the base of the triangle is 10 meters, what is the height of the triangle?

12

Step-by-step explanation:

Divide the triangle into two right triangles.

Then use Pythagorean theorem for calculating the missing side (which is the height) of one of the right triangles.

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
