If the lamppost is not the light source then lampost's shadow is 112/(64/20) ie 35 inches.

If a 5 ft post cast a shadow of 1.2 ft find the length of the shadow for a 17 ft post?
The length of the shadow is proportional to the height of the post. Thus, if l is the length of the unknown shadow, l/17 = 1.2/5 or l = 4.1 feet. This should be rounded to 4 if the value 5 is not considered to be known to at least two significant digits.
What will be the shadow length at 4 pm?
The answer depends on: the height of the item casting the shadow, the location on earth, the time of year, and the inclination of the surface on which the shadow is cast.
How high is a tree that casts a 25ft shadow?
You need more information to solve this problem. The length of a shadow depends on the angle of the sun which depends on the time of day.
A 3 foot pole casts a 6 foot shadow A 4 foot pole casts an 8 foot shadow Use a linear equation to predict the length of a shadow cast by a 6 foot pole?
Shadow lengths are proportional to the heights of objects casting the shadows. Therefore, calling the shadow length l, the height h, and the proportionality constant k, l = kh. (The intercept is 0 because an object with no height casts no shadow.) Therefore, in this instance k = l/h = 6/3 or 8/4 = 2. then l(6) = 2 X 6 = 12 feet.
Why does the length and position of my shadow change as I walk towards a lamppost and away from the lamppost?
Light leaves the lamp and travels in straight lines from its point source. As you move away from the source, the angle between you and the light changes and this the length and position of your shadow changes.

The light from a lamppost casts a shadow of a man who is standing 10 feet away from the lamppost. The man's shadow is 5 feet long. The angle of elevation from the tip of the shadow to the lamp is 50 d?
The man is 5.96 feet tall and the lamp is 17.88 feet high.
A person of height 1point72 m is walking away from a lamppost at 1 m per s the light on the lamppost is 5 point 8 m above the ground at what rate is the length of the persons shadow changing?
That rate changes as the person's distance from the lamp-post changes. If you specify how far away he is from the lamp-post at some instant in time, we can calculate how fast the length of his shadow is changing at that same instant. This is a perfect example of a simple differential calculus problem.
To obtain the height of a tree you measure the tree's shadow and find that it is 8 meters long the shadow of a two-meter lamppost and find that it is 75 centimeters long how tall is the tree?

If a nail is 50 millimeters in length what is its shadow length in millimeters?
Its shadow will be 50 millimeters in length, if you lay it down on a flat surface.
How does the length of a shadow change during the yearwhy does this happen?
The length of the shadow (on a flat, horizontal floor) depends on the height of the Sun. If the Sun is higher in the sky, the shadow will become shorter.
Does the length of a sun stick control the distance a shadow moves?
yes the length of the sun stick does control the distance the shadow moves

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.
A tree is twice as high as the length of the shadow it casts The distance from the tip of tree to the tip of the shadow is 8 feet What is the length of the shadow that the tree casts?
We can not tell because we do not know how straight the tree is or if the ground is perpendicular or level.
