how do i find the size of an object based on the size that I see it as?
Brett asked:
This is like a golf pin range finder. I know the height of the object, 28 inches, and I know that i'm looking through the range finder tube at about 12 inches. What would the height of the object be when I'm looking thru the tube at 20 yards (720 inches)?
