Hello!
The angle of incidence may not be equal to the angle of emergence. This is only the case in a glass slab. In prisms we can use the formula
A + d = I + e
Where a is the angle of one vertex of the prism, d is the angle of deviation and I and e are the angles of incidence and emergence respectively.
Hope this helps!
