Two sheets of polaroid are oriented so that there is a maximum transmission of light. One sheet is now rotated by 30 degrees, by what factor does the light intensity drop?

OK, the only equation I could think to use is tanB = N1/N2 but it doesn't seem to work.

the answer is 0.75 I just can't seem to get there.

Any help would be GREATLY appreciated.
