What else can I help you with?
At a certain distance the angle of elevation to the top of a building is 60 From 40ft further back the angle of elevation is 45 Find the height of the building?
Angle of elevation: tangent angle = opposite/adjacent and by rearranging the given formula will help to solve the problem
Measure of change in elevation in a certain distance is called what?
The measure of change in elevation in a certain distance is called slope. It is typically expressed as the ratio of the change in vertical height to the horizontal distance between two points on a surface.
Change in elevation over a certain distance is called?
Gradient
What is change in elevation called?
the measure of change in elevation in a certain distance is called gradient
Is distance always relative?
Distance is a measurement of the space between two points, which can be objective and not always relative. However, in certain contexts, distance can be subjective or appear to vary depending on the observer's frame of reference.
To take a clear picture of an image in a mirror should the camera be focused on the image or the mirror?
An image in a mirror is a "virtual" image which takes on certain characteristics. One of these characteristics is that the apparent distance is equal to the distance from the observer to the mirror plus the distance from the mirror to the subject. If the observer and subject are the same, then the apparent distance is twice that of the subject to the mirror. If the observer is 3 feet from the mirror and the subject is 20 feet away, the apparent distance is 23 feet. If you focus on the subject and have distance markings on your lens, you can prove this to yourself.
Is elevation the steepness of land?
No, elevation refers to the height of a landform above a reference point, usually sea level. Steepness of land is usually measured by gradient, slope, or incline, which quantifies the change in elevation over a certain distance.
What is the definition of elevation?
It depends upon the context. In mathematics, elevation usually refers to how much something is raised, and the angle of elevation would be the angle between the horizontal and the direct line to the object. In ballistics, elevation is the angle of elevation of mathematics. In architecture, it refers to a vertical aspect of something, e.g. the front elevation of a house would be the vertical front of the house as someone looks at it from the street. In cartography (map making), elevation would usually refer to how high something is above [mean] sea level.
What does an elevation map do for you?
an elevation map shows you the different heights of a certain area
What is a measure of the change in elevation over a certain distance?
This is mathematically known as slope or "rise/run".
A mesure of the change in elevation over a certain distance?
The rate at which elevation changes over a specified horizontal distance is known as slope. It is commonly expressed in terms of degrees or as a ratio (e.g., 1:10). Slope is an essential factor in determining the steepness of terrain and is used in various fields such as geography, engineering, and outdoor recreation.
How do you find length of a tree?
Using trigonometry. By measuring a certain distance from the tree and knowing the angle of elevation you can use the tangent ratio: tan = opp (the height of the tree)/adj (the distance) Rearrange the formula: opp = adj*tan
