Answer #1

Note that refractive index depends on wavelength and that it is unspecified in the question. But we're will assume it's monochromatic.

Let n1 and n2 represent the refractive index of the two media.

Brewster's angle,

And, critical angle,

Here the critical angle is 37°.

Therefore,  

  

Now, Brewster's angle, = 31.04°
