If the angle at the top of the tower is known, a surveyor would use the a0 function9 to find the length x. The cosine of a 50° angle is a1 this represents the value created when length a2 is divided by a3 feet. If the angle near the top of the tower was changed to 60°, the cosine would be 0.5; now the length of x would be a4 feet. If the angle near the top of the tower was changed to 60°, the angle from the light and the ground would be a5 degrees.

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

step-by-step explanation:

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
