A Laser Produces Linearly Polarized Light That Is Polarized in the Vertical

A laser produces linearly polarized light that is polarized in the vertical direction.The light travels in the +y-direction and passes through two polarizers.The polarization axis of the first polarizer is tipped towards the negative x-axis at 24 ^$\circ$ from vertical (z-axis) .The polarization axis of the second polarizer is tipped towards the positive x-axis at 15 ^$\circ$ from vertical (z-axis) .The laser beam is collimated (neither converging nor expanding) ,has a circular cross section with a diameter of 1.00 mm,and has an average power of 15 mW.What is the average power of the laser beam after passing through both polarizers?

A) 3.75 W
B) 7.56 W
C) 10.6 W
D) 11.7 W
E) 12.5 W
