A person does a handstand with his feet touching a wall and his hands 1.8 feet away from the wall. If the person is 5 feet tall, what angle does his hands make with the ground

68.89 degrees

Step-by-step explanation:

Given that,

A person does a handstand with his feet touching a wall and his hands 1.8 feet away from the wall.

A  person is 5 feet tall

We need to find the angle his hands make with the ground. Let it is . Here, 5 ft will be hypotenuse and 1.8 ft will be base of a triangle. Using trigonometry we get :

So, his hands will make 68.89 degrees angle with the ground.

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
