# Quick Answer: When The Length Of The Shadow Of A Pole Is Equal To?

## When the length of the shadow of a pillar is equal to its height the elevation at Source of sight is?

The height of pillar, and the length of the shadow are equal to each other.

Therefore, the angle of elevation of the pillar from the source of sight is 45°, making the answer Option(b) 45°..

## What is the length of altitude of equilateral triangle?

Formulas and Calculations for a equilateral triangle: Altitude of Equilateral Triangle h = (1/2) * √3 * a. Angles of Equilateral Triangle: A = B = C = 60° Sides of Equilateral Triangle: a = b = c.

## When the length of shadow of a vertical pole is equal to √ 3 times of its height the angle of Elevat?

tanθ=ABAC=√3xx=√3⇒θ=60∘.

## 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 °.

Transparent objects cannot form a shadow. They are only formed in opaque or translucent objects. If we take a glass slab, no shadow is formed because it allows light to pass through it.

## On which angle the length of a pole is equal to its shadow?

In right angle ΔABC, AB represents the vertical pole and BC represents the shadow on the ground. θ represents angle of elevation the sun. But length of shadow = height of the tower, i.e. h = x. Thus, angle of elevation of the sun = 45°.

## What is the length of the shadow?

The length of shadow to your height is proportional to 1/Tangent (sun’s altitude). If the sun is low in the sky (10 degrees), your shadow would be 5.67 times as long as your height. The corresponding ratio at 5 degrees is 11.43 . (So an average height person (5.8 feet) would have a 66 foot long shadow).

## When the length of the shadow of a pole is equal to root 3?

question_answer Answers(3) ∠ACB = 30°. ∴ height of shadow =√3h . ∠ACB = 30°. Therefore, angle of elevation is 30°.

## Why is the length of shadow smallest at noon?

shadow is shortest at noon. at noon, the sun is directly overhead. so the rays fall vertically on the body. in mornings and evenings, the rays fall at inclined position.

## What is Angle elevation?

The term angle of elevation denotes the angle from the horizontal upward to an object. An observer’s line of sight would be above the horizontal. The term angle of depression denotes the angle from the horizontal downward to an object.

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

Hence, the angle elevation is 45o.

## When the length of the shadow of a pole of height 10m is equal to 10m then the angle of elevation of source of light is?

Answer. The source of light must at an angle of 45 degrees that is why the length of the shadow is equal to the length of the ploe.

## What will be the angle of elevation of sun?

Complete step-by-step answer: Here,∠B = 90∘ makes the triangle a right angled triangle. Hence the angle of elevation of sun is 45∘.

## What is the length of a shadow at noon?

In this example, it is learned that the length of the shadow cast by the 790-foot high Prudential Tower in Boston on June 21, 2011, at noon is approximately 273.36 feet.

## When the length of the shadow of a vertical pole is equal to?

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