Question

To determine the refractvie index of a glass slab, an experiment was done. when the result is graphed, the slope is the refractive index of the medium. This soultion was given to me (2nd pic) as an explanation. however, i do not understand why sin theta 1/ sin theta 2 coresponds to the rise over run. would u explain it? thanks
