you must have your lenght and hypotenus and use the pythagorean thearom to figure it out
a2 plus b2= c2
===========================
Answer #2:
The first answer is technically correct, and in the practical sense, totally useless.
Without using your shadow, plus a rather difficult measurement, you don't have
the length of the hypotenuse. If you're willing to go to that much trouble, you
might as well measure the shadow and be done with it.
Here's an alternative proposal. It requires that you know your own height, and
have either your calculator in your pocket, or your slide rule dangling from your
belt. If you have a window, then you can do it without even going outside:
-- Measure or estimate the sun's "altitude" ... its angle above the horizon.
-- Divide your height by the tangent of the sun's altitude.
-- The quotient is the length of your shadow on flat, horizontal ground.

What three things do length and position of a shadow changing depend on?
The length and position of a shadow depend on the angle of the light source, the distance between the object and the surface the shadow falls on, and the height of the object casting the shadow.
what causes shadow length?
The length of a shadow is primarily determined by the angle of the sun in relation to the object casting the shadow. Shadows are longer in the early morning and late afternoon when the sun is lower in the sky, and shorter at midday when the sun is directly overhead. The size and shape of the object casting the shadow also play a role in determining shadow length.
What is the relationship between the size of the shadow and the distance of the object from the light source?
The relationship between the size of a shadow of an object and the distance of light source from the object is indirectly proportional. A short distance will make the shadow big while making the distance long will reduce the size of the shadow.
How does sunlight affect the appearance of my shadow?
Sunlight affects the appearance of your shadow by casting it on the ground when an object blocks the light. The position of the sun in the sky determines the length and direction of your shadow. The angle of the sunlight also affects the sharpness and darkness of your shadow.
Why does the length and position of my shadow changes as I walk towards and away from the lamp post?
The length and position of your shadow change as you walk towards or away from a lamp post because the angle of the light hitting you changes. When you are closer to the lamp post, the angle of the light hitting you is more direct, resulting in a longer shadow. As you move away, the angle becomes more oblique, shortening the shadow.
How can you find the height of tree?
Using trigonometery if you know the length of its shadow and angle of elevation
What would be the length of the shadow of a 24 ft tree when a 40 ft tree casts a 16 ft shadow?
You have two similar triangles with one side the tree, and another the shadow Using the side with the tree, the ratio of the length of the triangles can be found: the triangles are in the ratio of 24 : 40 Thus divide the shadow of the 40ft tree by 40 to find out the length of shadow per foot of tree, and multiply this by 24 to find the length of the shadow of the 24 ft tree. This can be done by using the ratio as a fraction 24/40: → the shadow of the 24 ft tree is 16 ft × 24/40 = 9.6 ft
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.
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.
The tallest free-standing structure in the world is the 553 meter high CN Tower in Toronto What will be the length of the shaddow of the tower on a day that the angle of 50?
To find the length of the shadow of the CN Tower when the angle of elevation is 50 degrees, you can use the tangent function. The formula is: shadow length = height / tan(angle). Thus, the shadow length would be approximately 553 meters / tan(50°), which is about 553 meters / 1.1918, resulting in a shadow length of approximately 464 meters.
What three things do length and position of a shadow changing depend on?
The length and position of a shadow depend on the angle of the light source, the distance between the object and the surface the shadow falls on, and the height of the object casting the shadow.
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
At any given time of the day the ratio of an object the length of its shadow is the same for all objects if a 5ft post casts a shadow of a 1.2ft find the length for a 17ft post?
Let the length of the shadow be x and use the tangent ratio: 5/1.2 = 17/x Make x the subject of the equation: x = (17*1.2)/5 x = 4.08 feet
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?
Since the tree is twice as high as the length of the shadow, we can set up the following equation: 2x = x + 8, where x is the length of the shadow. Solving the equation gives us x = 8 feet, so the length of the shadow that the tree casts is 8 feet.
What is the length of your shadow at midday?

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.
