Angle of incidence / angle of refraction practice problems

Light travels from glass into diamond with an angle of incidence (θi) of 52.3 °. What is the angle of refraction (θr) if the refractive index of glass is 1.5 and the refractive index of diamond is 2.4.

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