Unpolarising light on two polarizing sheets so oriented that is transmitted. If a third polarizing sheet is placed between them, not parallel to either of the above two sheets in question

Unpolarised light falls on two polarizing sheets placed one on top of the other. What must be the angle between the characteristic directions of the sheets if the intensity of the final transmitted light is one-third the maximum intensity of the first transmitted beam?
