The height of a flagpole is 22 feet. from a distance of point x on the ground, the angle of elevation is 55°. from a further distance of point y on the ground, the angle of elevation is 20°. what is the distance from point x to point y to the nearest foot?

The distance from x to y is 45ft.

Step-by-step explanation:

Use the trigonometric function tangent. In this setting, the tangent of the angle of elevation is the ratio of the flagpole height and the distance of the observer. So we know that for point x and for point y, the following is true:

each of which lets us solve for the unknown:

The distance from x to y is 60.4-15.4=45ft.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

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
