Snell's law:

$\overline{){{\mathbf{\eta}}}_{{\mathbf{1}}}{\mathbf{s}}{\mathbf{i}}{\mathbf{n}}{{\mathbf{\phi}}}_{{\mathbf{1}}}{\mathbf{=}}{{\mathbf{\eta}}}_{{\mathbf{2}}}{\mathbf{s}}{\mathbf{i}}{\mathbf{n}}{{\mathbf{\phi}}}_{{\mathbf{2}}}}$

Where φ_{1} is the angle of incidence, φ_{2} is the angle of refraction, η_{1} is the refractive index of medium 1 (water), and η_{2} is the refractive index of medium 2 (air).

The angle underwater is φ_{1} = 90° - 59° = 31°

(1.33)sin(31°) = (1)sin(φ_{2})

An underwater diver sees the sun 59 degrees above horizontal.

What is the angle between the sun and the fisherman relative to the horizon?

Express your answer using two significant figures.
