The height of a boy that casts a 4 foot long shadow depends on the angle of the sun. A tangent can be used to calculate his height if we know the angle of the sun using the equation:
Height = shadow length x tangent of the angle of the sun.
Using a calculator, it is easy to get the value of the tangent for any angle and then complete the equation.
You take 280 times 10 and then divide that by 14 which equals 200 ft.
The height of the tree is in direct proportion to the pole and its shadow
(35/7)*4 = 20 Ft.
A stick is 6/4.5 = 4/3 times its shadow. So the tree is 4/3*25 = 33.3... feet or 33 ft 4 inches tall.
If the shadow of a 6-ft person is 4-ft long, then in this place at this moment, all shadowsare 2/3 the length of the vertical object that casts them.The 9-ft shadow therefore 2/3 the height of the tree. The height is (9)/(2/3) = (9 x 3/2) = 13.5-ft.-----------------------------------------(9/4)*6=13.5 ft.
32
It is approx 36.6 ft.
1. How high is a flagpole that casts a shadow of 45 ft at the same time a woman 5.5 ft tall casts a shadow 10 ft?
13ft
x/85 = 6/17 30 ft.
It is 90 feet in height
You take 280 times 10 and then divide that by 14 which equals 200 ft.
36.0 feet
The tree is 36.0 feet tall using the tangent ratio.
If the building casts a shadow, then the sun is out, and any man who is not standing in theshadow of the building will cast a shadow of his own, no matter how short or tall he may be.(If you had told us the length of the man's shadow, it would have been a completely differentquestion, and we could have had a completely different answer to offer in response.)
If a 27 ft tall pole casts an 18 foot shadow, a 63 ft tall pole casts an x foot shadow.Put 27/18 and 63/x.Cross multiply, get 27x=1134Divide by 27 on both sides, a 63 foot tall pole casts a 42 foot long shadow.
40 ft
