Snell's Law -synthesis calculations

Light travels from fiber optic cable into water with an angle of incidence (θi) of 32.7 °. What is the angle of refraction (θr) if the refractive index of fiber optic cable is 1.6 and the refractive index of water is 1.33.

The angle of refraction is: ° (Give your answer to the nearest 10th of a degree)
