What is the length of the shadow of a building having 10 Metre height if the angle of elevation of the sun is 45 degree?

In figure, AB is the tower and BC is the length of the shadow when the Sun’s altitude is 45°, i.e. the angle of elevation of the top of the tower from the tip of the shadow is 45°. Thus, the height of the shadow is 10 m.

What will be the length of the shadow of 10 m high tree if the angle of elevation of the sun is 30?

Hence, the length of the shadow of 10m high tree is 20 m.

What is the length of the shadow of the pole?

The length of a shadow of a pole is √(3) times the length of the pole.

How can this difference in the length of your shadow be explained?

The explanation is partial. If you go outside on a sunny day, you will make a shadow. At some times of day your shadow is longer than you are. Scorer Comments: Student response explains that the rotation of the Earth causes the Sun’s light to hit the Earth at different angles, affecting the length of the shadows.

How do you calculate area of a shadow?

If the candle is placed at the center of the top surface, let the distance from the origin (center of the surface) to the end of the shadow be r. In this case the area of the shadow can easily be calculated by the difference of 2 circular areas ie:- πr2− Area of cylinder’s base.

What is the length of the shadow of the tower when the angle of elevation of the sun is 30 degree?

If Sun’s elevation with respect to ground is 30°, then ∠C=30°. The diagram is, Let the tower’s length be x, and CD is shadow’s length = 30m.

When the length of the shadow of a pole is equal to √ 3 times the heights of the pole then find the angle of elevation of source of light?

Let the height of the pole ( AB) = h . Let ϴ denotes the angle of elevation of the Sun. Hence , the angle of elevation of the Sun is 30 °.

When the length of the shadow of a pole of height 20 √ 3 m is equal to 20 m then the angle of elevation of the sun is ____?

Answer Expert Verified Let ϴ denotes the angle of elevation of the Sun. Hence , the angle of elevation of the Sun is 30 °.

What is the length of the shadow of an 8 m high tree when the sun’s altitude is 30 degree?

30 किमी० चलने में X को Y से 3 घण्टे अधिक लगते हैं।

When the length of the shadow of a pole is equal to a height of the pole then the elevation of source of light is?

∴The angle of elevation of source of light is 60∘

When the length of the shadow of a pole is equal to the height of the pole?

If the length of shadow of a vertical pole is equal to its height, then the angle of elevation of the sun is 45o.

What is the length of the shadow of a 15m high pole?

Length of the shadow of a 15 meter high pole is 5√ (3) meters at 7’o clock in the morning. Then what is the angle of elevation of the Sun rays with the ground at that time?

What is the angle of elevation of the Sun?

If the length of the shadow of a pole is equal to the height of the pole, then the angle of elevation of the sun is 10th

What is the unit of measurement for the height of Sun?

The height of the Sun is given in degrees. Object height and shadow length have the same unit, e.g. feet or meters. See also shadow length and direction by coordinates and time. ft, m, ft, m,

How do you calculate the length of a shadow?

Sun altitude and shadow. This simple online calculator gives a vertical object shadow length for specified day and geographic coordinate. The calculator uses Sun position algorithm to calculate sun altitude. Then it uses this formula to calculate shadow length: , where. h – object height, a – angle between Sun and horizon.
