180 - 75 equals 105. divide 105 by 2 equals 52.5. set yer sharpener @ 52.5 on the left & right. the 2 grinds will give you a 75 degree graver.

If you want full-sided parallel heels on the graver, rather than the short-sided traditional triangle heel, you will need to rotate the graver over more than the 52.5 degree side shape angle. Attached is a PDF showing required rotation angles for vee gravers in 5 degree increments from 60 to 130 degrees vee angle and 45-50 degree face angles
