What is the height of the telephone pole if shadow is 20 feet long and the angle of elevation from the groung if 70 degrees?
Using the tangent ratio height of telegraph pole is 55 feet to the nearest integer.
When is the shadow equal in length to your height?
When the angle of elevation equals 45 degrees. tan-1(1) = 45 degrees.
At a certain time of day the angle of elevation of the sun is 30 degree A tree has a shadow that is 25 feet long Find the height of the tree to the nearest foot?
Tan60= 25/Height. Height = 25/Tan60 = 14.43
When the angle of elevation on of the sun is 75 degree a building casts shadow of 125 feet how tall is the degree?
If you mean the height of the building then it works out as 466.5063509 feet
When the angle of elevation to the sun is 52 degrees a tree casts a shadow that is 9 meters long what is the height of the tree?
It is: tan(52)*9 = 11.519 meters rounded to three decimal places
What is the height of the telephone pole if shadow is 20 feet long and the angle of elevation from the groung if 70 degrees?
Using the tangent ratio height of telegraph pole is 55 feet to the nearest integer.
Suppose you know the height of a flagpole on the beach of the Chesapeake Bay and that you know the length of its shadow How do you calculate the angle of elevation?
If you also know its shadow then you can work out the angle of elevation
How can you calculate height of a pyramid by measuring the length of its shadow?
By means of trigonometry if you know the angle of elevation or by comparing it with a nearby object if you know its height and shadow length.
How can you find the height of tree?
Using trigonometery if you know the length of its shadow and angle of elevation

How tall is a building with a 73 ft shadow when elevation of the sun is 31 degrees?
(Height of the building)/(length of the shadow) = tangent of 31° .Height = 73 tan(31°) = 43.9 feet (rounded)
How do you measure wood size?
By its shadow :) Then I measure mine shadow, or shadow of any object I know how high is.. and use proportion: HW/MH=WS/MS or HW=MH x WS/MS HW=wood height MH=mine height WS=length of wood shadow MS=length of mine shadow
When is the shadow equal in length to your height?
When the angle of elevation equals 45 degrees. tan-1(1) = 45 degrees.
What unit of measure for height of a tree?
Hold a yardstick perpendicular to the ground, and measure the shadow. Make a proportion, then measure the tree's shadow. Use the proportion to compute.
How could you measure the height of a tree at noon when the sun is directly overhead and the tree casts no shadow?
Your best bet here would be to use trigonometry. One stand a given distance away from the tree and sight the top of the tree, say with a clinometer, to measure the angle of elevation. Then knowing the angle and the distance you are from the tree, the height of the tree can be calculated with a tangent function.
If the angle of elevation of the sun is 53 degrees when a flagpole casts a shadow of 12 m then the height of the flagpole is?
The flagpole is 15.92 metres, approx.
At a certain time of day the angle of elevation of the sun is 30 degree A tree has a shadow that is 25 feet long Find the height of the tree to the nearest foot?
Tan60= 25/Height. Height = 25/Tan60 = 14.43
