Two polaroids are crossed to each other. One of them is rotated through 60^(@) , what % age of incident unpolarised light will pass through the system ?

Two polrizers are oriented with transmission planes making an angle of 60^(@) . The percentage of incident unpolarized light that passes through the system is

Three polaroids are placed one above the other, such that the first and the last polaroids are crossed with each other. If the angle between the transmission axis of the first two polaroids is 45^@ , then what is the percentage of incident light transmitted through the combination of three polaroids ?
