Suppose the incident beam of light is linearly polarized in the same direction as the transmission

Question:

Suppose the incident beam of light is linearly polarized in the same direction θ as the transmission axis of the analyzer. The transmission axis of the polarizer remains vertical.
(a) What value must u have if the transmitted intensity is to be 0.200 I0?
(b) If u is increased from the value found in part (a), does the transmitted intensity increase, decrease, or stay the same? Explain.
