A Geiger-Marsden experiment, in which alpha particles are scattered off a thin gold film, is set up

Question:

A Geiger-Marsden experiment, in which alpha particles are scattered off a thin gold film, is set up with two detectors at θ1 = 85.1° ± 0.9° and θ2 = 62.9° ± 0.9°. Assuming that the scattering obeys the Rutherford formula, what is the ratio of the measured intensities, I1 / I2?
