Question

in an experiment with a glass slab a student observed that a Ray of light is incident at an angle of 60 with the normal on one face of the slab after refraction strikes the opposite face of the slab before emerging out in air making an angle of 42 degree with the normal draw a labelled diagram to show the part of this Ray what would be the value of angle selection and angle of emergence​
