Angle at which under water diver sees the sun from horizontal = $57^{0}$

Angle from normal direction = 90 - 57 = $33^{0}$

Refractive index of water = 1.33

Refractive index of water = 1

We have the equation

1.33 * sin $33^{0}$ = 1 *sin $\alpha$

$\alpha$ = $sin ^{-1} (\frac{1.33sin33}{1} )= 46.42^0$

This angle is angle from normal, so angle seen by fisherman from horizontal = 90 - 46.42 = $43.58^{0}$
