Question

A student carries out the experiment of tracing the path of a ray of light through a rectangular glass slab, for two different values of angle of incidence: angle i=30o and angle i=45o.The set of values of the angle of refraction and the angle of emergence,she is likely to observe in the two cases,are
A)angle r=20 ,angle e =30 and angle r=28 , angle e=45
B)angle r=30, angle e=20 and angle r =45,angle e=28

how to find the angle of refraction? pls eplain.
