Here I used your data although I am not sure about #n=51.458# for quartz....I am almost poitive that is not right!
For #n_1# I used air.
If you have other data simply use them into the derivation.

Explanation:

Brewster's Angle is a special incidence angle from which unpolarized light emerges polarized (in reflection and refraction).
The idea is the the two beams (reflected and refracted) will form an angle of 90° when incidence is at Brewster's angle:
