What is a formula to calculate the perceived size of an object depending on its distance?

The perceived size is usually measured in terms of the angle subtended by the object at the observation point.
Suppose an object of length L, is at a distance D. Then the angular size perceived by an observer who is along the perpendicular bisector of the object, is 2*arctan(L/2D). The formula holds for small divergences from the perpendicular bisector but not significant ones.
For example, for a person standing near the base of a tower, the perceived size is arctan(L/D).

If the formula to calculate work is distance divided by time how do you apply the formula?
You would have a very tough time, because that isn't the formula to calculate work. (distance) divided by (time) is the formula to calculate speed. The formula to calculate work is: (force) multiplied by (distance).
How do you calculate the formula for distance?
== I'm pretty sure the formula for distance is: D== rt (Distance= rate x time) == The formula for distance is: speed x time.
What formula do you use in science to find the distance?
In science, you can calculate distance using the formula: distance = speed × time. This formula relates the distance traveled by an object to its speed and the time it takes to travel that distance.
What is the formula to calculate area of an object?
A=lw or a different formula depending on the object
What is the formula to calculate length of the wire?
There is no formula to calculate the length of a wire. The length of a wire is determined by the distance from the power source to where the load is situated.
What is the formula for finding speed?
The formula for finding speed is speed = distance/time. This formula is used to calculate the rate at which an object is moving over a certain distance in a specific amount of time.
How do you find distance in the formula work equals force times distance?
To find distance in the work formula, you can rearrange the formula to distance equals work divided by force. This allows you to calculate the distance by dividing the work done by the force applied.
How can you calculate the distance using the formula?
There are several formulae for different cases. For the case of a constant speed, use the formula: distance = speed x time.
Formula to calculate distance between planets?
The parallax method can be used to calculate the distance between planets and other celestial bodies. The formula for this is d(pc) = 1/p where p is parallax measured in arcseconds.
