This angle is termed as Altitude.
It's the arctic circle. (the other one is the antarctic circle) They're 23 degrees away from the poles, 'cause that the angle of tilt on the Earth.
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.
Elevation Prevailing Winds and Angle
Lines of latitude are imaginary lines that run parallel to the equator and form part of a grid used to describe where on the earth you are. They are often called parallels.
Angle of elevation is looking upwards to an object and angle of depression is looking downwards to an object
The angle of elevation is looking at an object above your line of sight.
distance and angle of elevation are closely related as the more closer you move, the half is the angle of elevation. for e.g. if you travel 30m and cover 15m then, the angle of elevation will be half of what you started with. this can be also proved by a live example as when you have the angle of elevation as 90 degree, then the distance can be zero....
It is the alternate angle to the angle of elevation
Central Angle An angle in a circle with vertex at the circle's center.
If the base of the elevation is at a distance d from the observer, then the highest point is at a height = d*tan(angle of elevation)
Central Angle
They are quite similar but a angle isbasically part of the circle. if a had an angle of 90 degrees then it is aquarterof the circle. the circle it the whole thing and the angle is part of the thing
Angle of elevation: tangent angle = opposite/adjacent and by rearranging the given formula will help to solve the problem
A sextant.
An inscribed angle is an angle with its vertex on a circle and with sides that contain chords of the circle.
Radius: A line from the center of a circle to a point on the circle. Central Angle: The angle subtended at the center of a circle by two given points on the circle.
