Light is reflected by two flat mirrors that have an angle q = 114 degrees between them. If the initial ray makes an angle qin = 66 degress with respect to the normal, what is qout?

I know that the angle of incidence is equal to the angle of reflection, so I thought that qout would also be 66 degrees, but that is not the answer, so i am a bit confused.
