1. The problem statement, all variables and given/known data
Here is the original problem: https://www.physicsforums.com/showthread.php?t=272077
This is the part I need help with (bolded):
The image of the D and VP (thoguh I've already done it, I found another document after I was complete--what a shame--that had a similar almost same diagram for the D and VP parts: http://www.math.nus.edu.sg/aslaksen/projects/ykk-urops.pdf
(page 27)
2. Relevant equations
magnification: m = $$\frac{d_{i}}{d_{o}}$$

3. The attempt at a solution
I found m: 5.2 (you may check, I used hight to find it, and measuring from the skecth graph) I want to know how to find either $$d_{i}$$ or $$d_{o}$$ and which one I should find first.

Thanks!
