An angle of declination is relevant when an observer is at a higher altitude than the object being observed. It is the angle made by the line of sight with the horizontal. Suppose this is angle x. Then if the altitude of the observer is known to be h, then line-of-sight distance to the object is h*sin(x). The object is h*tan(x) from the point below the observer at the level of the object.
Conversely, if the line-of-sight distance from the object to the observer or the horizontal distance to the point directly below the observer is known, it is possible to calculate the height of the observer.

How is the altitude angle and zenith angle related to latitude and declination?
solar altitude angle= (90 degree - zenith angle )
How can you use a right angle to decide to name another angle?
If the angle is larger than a right angle it is obtuse
Why can not use second angle and four angle projection method in Engineering drawing?
Because in second angle both quaderent comes negative that's why we cant use second angle method
How do you know when to use the big or small numbers on protractor when measuring an angle?
When the angle you are measuring is obviously an obtuse angle (angle above 90 degrees, or when you draw a box in the angle and it turns out bigger than it's supposed to) you use the big numbers. When the angle is obviously acute (opposite definition of obtuse), you use the little numbers.
How can you use a right angle to determine the classification of another angle?
An acute angle is smaller than a right angle.An obtuse angle is larger than a right angle.^_^
