An unpolarized light beam traveling along the x-axis is sent into a system of three polarizers. The polarization axis of the first polarizer makes an angle of 15.4 degrees (measured clockwise) with the y axis. The polarization axis of the second polarizer makes a 32.6 degree angle (measured clockwise) with the y axis and the third polarizer's axis makes an angle of theta degrees (measured clockwise) with the polarization axis of the second polarizer. The intensity of the light emerging from the third polarizer is 0.11 of the intensity of the original unpolarized light. What is the measure of angle theta (measured clockwise) from the y-axis? Give your answer in the form "ab.c" degrees.
