From Snell's, we know that the ration of sine of incidence angle to the sine of refracted angle is a constant given by ratio of refractive indices of two medias: It is given that the reflected and refracted ray suffer equal deviation. This means the angle of reflected ray is equal to the angle of refracted ray = 70°.
