Initially unpolarized light is sent along the z-axis into a system of three polarizing sheets placed perpendicular to the z-axis and whose polarizing angles with respect to y-axis are 22° (first sheet), 89° (second sheet), and 56° (the last sheet). What percentage of the initial light intensity is transmitted by the system? Express your answer as a percentage, to at least one digit after the decimal.
