Refraction Through a Prism

In a laboratory experiment, a beam of light passes through a glass prism, which has a refractive index of 1.5. When the light enters the prism, it bends towards the normal line due to a decrease in speed, and when it exits, it bends away from the normal line as it moves into air, which has a lower refractive index. The angle of incidence from the first medium to the prism is 30 degrees.

What is the angle of refraction as the light exits the prism into the air?
