Angles geometry, what is it?

57

Step-by-step explanation:

If m<HIC is 99, so m<EIC is 81 (bc m<HIC + m<EIC = 180)

so m<GIH is also 81

m<HGI is the same with m<DGB =42

so:

42 + 81 + x =180

x = 180 - 42 - 81

x = 57

i believe that the answer is

b. y-1=-2(x-4)

hope this !

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
