3 yards in height

Ten is to two as 40 is to x, yielding: 200ft.
Using trigonometry its height is 12 feet
inverse of tan(h/6). where h=height of street post in meters.
Height of building/105 = 6/14 Multiply both sides by 105: Height = 630/14 Height = 45 feet
(35/7)*4 = 20 Ft.

The height of the tree is in direct proportion to the pole and its shadow
A 1 foot shadow I think.
It is 90 feet in height
It works out as 12 feet and 4 inches in height
Ten is to two as 40 is to x, yielding: 200ft.
Using trigonometry its height is 12 feet
inverse of tan(h/6). where h=height of street post in meters.
Height of building/105 = 6/14 Multiply both sides by 105: Height = 630/14 Height = 45 feet
It depends on the time of day because the angle of the sun will determine the shadow length
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.
