Ratio of light waves amplitude question

I've been given a graph that's similar to the graph for this question:

A beam of polarised light is directed normally at a polarizing filter of cross sectional area 9.0 x 10^-4 m^2. the polarizing filter is slowly rotated in the plane at right angles to the beam. the transmitted intensity I plotted against the angle x resembles [the graph I mentioned] with a maximum intensity of 20 Watts per square metre, use the graph to calculate the ratio of the amplitude of the light at 0 and 60 degrees ( 0 degrees / 60 degrees)

Please help me figure this out 😄
Consider the component of light that gets through at 60 degrees: you can do this and then work out the ratio. You'd only need the angles, not the rest, but I assume the rest is for another part of the question.
