We know , for a start , the angle of incident ray on the 1stmedium. To solve the problem we need to know the refractive index of all the three medium here. If we know the refractive index of all the three medium then we can calculate the angle of refraction of each of emergent ray .Emergent ray from the interface of 1stand 2ndmedium becomes the incident ray for interface for 2ndand 3rdmedium.
Through this we can caluclate the angle between the emergent ray and the incident ray.
