Find the size of an angular object?

To find the size of an angular object, you can use the angular size formula, which relates the actual size of the object to its distance from the observer. The formula is given by: angular size (in radians) = actual size / distance. To convert radians to degrees, multiply by 180/π. By measuring the angular size and knowing the distance, you can rearrange the formula to solve for the actual size of the object.
