## How tall is a building that casts a 74 ft shadow when the angle of elevation of the sun is 32?

Question: How tall is a building that casts a 74-ft shadow when the angle of elevation of the sun is 30°? The building is□fttall.

How tall is a building that casts a 77 ft shadow when the angle of elevation of the sun is 33?

Thus, the height of the building is 54ft.

When the sun’s angle of elevation is 57 the building casts a shadow 21 meters long How high is the building?

32m
When the sun’s angle of elevation is 57, a building , casts a shadow 21 m long. How high is the building? x = 32m Page 3 2.

### How can I find out the height of a building?

The height of the building is calculated by using the formula: Height of the building = y * tan x + measurer’s height. y = distance of the measurer from the building.

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).

What is the standard height of a building?

The floor-to-floor height is generally 7.5 ft in the case of residential building. On the other hand, the height of each story in commercial buildings is 10 ft [38] (see Fig. 2). The residential building has four floors, while the commercial one has three floors.

#### How do you find the height of a building without measuring it?

You can determine the height of a building without having to leave the ground, just by using simple trigonometric or geometric analysis. You can either use the building’s shadow, when the sun is high on a sunny day, or you can use a sextant to measure the angle to the top of the building.

Answer: Yes,Because of the movement of the light and motion of the body. Every time you move The shadow changes because The direction Of the light Has only 1 Direction.

How to calculate the height of the 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.

### How to calculate the angle of elevation of an object?

The angle framed by the line of sight and the horizontal (line from observer and object vertical point) is known as angle of elevation. It can be estimated from the known values of height and distance of the object. In other words, Angles of elevation or inclination are angles above the horizontal.

What is the angle of elevation of an aeroplane?

An aeroplane flies at a height of 100mm, the distance of the plane from the observers point of view is 123mm. Angle of Elevation = atan (100/123)
