Here's the print from TBLAP; red line points to extractor notch angle, yellow triangle is the ramp. 1.8mm on one side; 2.77mm on the other. It's a right triangle and the hypotenuse is not relevant - using trig table you can work out what the print says the angle is.

But in terms of case blowout, since the extractor cut is given as 53º, you really can't go too far wrong using that, if you don't like the trig answer.
