By means of trigonometry if you know the angle of elevation or by comparing it with a nearby object if you know its height and shadow length.
The relation between the arc of length and the central angle is that the arc of length divided by one of the sides is the central angle in radians. If the arc is a full circle, then the central angle is 2pi radians or 360 degrees.
a right angle or any other angle does not have a length. your question cannot be answered.
An acute angle is defined as an angle that measures less than 90 degrees. Therefore, its length is always between 0 and 90 degrees, not including 0 and 90 themselves. In terms of radians, an acute angle is between 0 and π/2 radians.

The relationship between focal length and angle of view is such that the shorter the focal length, the wider the angle of view. Shorter focal lengths encompass more of the scene in the frame, leading to a wider angle of view.

In a right triangle, the tangent of an angle other than the right angle is the ratio of the length of the side opposite the angle over the length of the side adjacent to the angle (the side between the angle and the right angle).

<ab> = |a|*|b|*cos(x) where |a| is the length of the vector a, |b| is the length of the vector b, and x is the angle between them.
The bond length is equal to the linear distance between the nuclei of the bonding atoms. The bond angle is equal to the angle between any two consecutive bonds in a molecule or ion. Bond angles of molecules and ions are usually determined by using the VSEPR theory.
An angle is measurement use to tell the distance between two lines that are concurrent at a point. An arc is the length of a curve drawn with a unchanging distance (radius length) around a point..
arc length/2pi*r=measure of central angle/360
An angle has no length at all. The angle is just the amount of opening between the two lines where they meet. The length of the angle's sides is completely irrelevant, and has no effect at all on the measure of the angle. They can be any length from almost zero to infinite, and they don't even have to both be the same length. It just doesn't matter. None of that changes the measure of the angle.
