It's angle of incidence will be

90°- 50°=40°

anne94: the normal makes angle of 90° with the glass slab.. but the incidwnt ray makes an angle of 50° with the glass slab... therefore angle of glass slab with normal = angle of incident ray with glass slab + the angle of incidence ... therefore..90°- 50°=40°
