Homework Statement
The figure illustrates qualitatively a converging lens focusing monochromatic rays from A to B. The vertical and horizontal scales of the figure are not the same. The top ray leaves A at an angle of 2.38 deg above the optic axis and leaves B at an angle of 1.25 deg below the optic axis. The total distance from A to B is 75.3 cm.

Calculate the focal length of the lens for that light.
Homework Equations
1/d0 + 1/di = 1/f
The Attempt at a Solution
I'm not even sure where to begin when I'm given the angles. I think 75.3 cm = d0 + di
but I'm not sure where to go from there
