When the angle of elevation equals 45 degrees.
tan-1(1) = 45 degrees.
volume is equal to length x breadth x height
area
It depends on the time of day, and, therefore, it depends on where the sun is in the sky.
no
That is how you find the volume of an object.
To find the height of a shadow, you can use similar triangles. Measure the height of the object casting the shadow and the length of the shadow itself. Then, using a known reference height and its corresponding shadow length, set up a proportion: (height of object)/(length of shadow) = (height of reference)/(length of reference shadow). Solve for the unknown height.
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.
Base times height tims width equal to length
Yes, a square prism's height, length, and width are equal.
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.
To find the height of the Gateway Arch, we can use the concept of similar triangles. The ratio of the boy's height to his shadow length is the same as the ratio of the Arch's height to its shadow length. Therefore, if the boy is 5 feet tall and casts a 1-foot shadow, the height of the Arch can be calculated as follows: Height of Arch = (Height of boy / Length of boy's shadow) × Length of Arch's shadow = (5 feet / 1 foot) × 126 feet = 630 feet. Thus, the Gateway Arch is 630 feet tall.
Its area is equal to its length, multiplied by its height
volume is equal to length x breadth x height
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.
area
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
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.
