In order to visually examine sunspots through a telescope we have to reduce the intensity of the sunlight to avoid harming our retina. To accomplish this intensity reduction astronomers have mounted two linear polarizers on their telescope. The second polarizer has its plane of polarization at an angle of 92.2" relative to the horizontal. If they want a reduction of the intensity of the sunlight by a factor 0.8697, what angle does the polarization plane of the first polarizer have to form with the horizontal? Give the angle in degrees and assume that 01
