We can solve the problem by using Snell's law:
where
is the refractive index of the first medium (in this case, air, so 
)
is the refractive index of the second medium (in this case, water, so 
)
is the angle of incidence of the light, with respect to the vertical, so 
is the angle of refraction of the light inside the water, with respect to the vertical
Re-arranging the equation and using the data of the problem, we can find the the angle of refraction of the light inside the water:
where
