It's an secant function where x is your angle and y is your distance.
You can see that after about 60 degrees it gets very inaccurate.
The IR sensor, on the other hand, is exponential decay, which makes a slightly friendlier curve. (Your error at 75% maximum distance is only +-25% of the total range of the IR sensor)
