Homework Statement
This was done on a sidewalk. Two boxes were set up a distance apart with one line on each box. We measured the distance of ten points going out from the boxes (ten cement tiles on the sidewalk) and were able to use a meter stick to measure by eye from each ten points the separation between the two lines on the boxes. So what I know is the separation I measured (from afar) using the meter stick, the length of my outstretched arms, and the distance each measurement was taken from the boxes. Attached is a picture of the triangle and variables drawn out.
ho= separation between two lines on boxes
d= distance from the point of the measurement to the boxes
x= length of my outstretched arms holding the meter stick
y= measurement taken by eye from the meter stick.
Homework Equations
I was given this equation h/d=y/x
but when I plug this in my distance between the two lines on the boxes continual increases when the distance away from the boxes increases, which is intuitive based on the equation.
3. Question
I know about triangulation, but this does not seem to deal with triangulation since we are not using angles, rather it seems to deal with trilateration, which I have not been able to find any useful information on google or anywhere. Could someone please help me figure out how to do this? My lab report is due tomorrow at 10:20AM and I have not been able to start since I do not understand the basis of measuring the distance between the two boxes using our knowns.
Please!
Thank you,
