incidence question, for geometry wiz's

[Terry Brox]

For all you mathematical intellectuals, I dont have an incidence meter that I feel too good about, so here is my question: I have a datum line drawn on the side of a fuse, a line parallel to the datum through the wing tube, and the distance from the center of the wing tube to the leading edge is 7". The plans call for 3/4 degree positive incidence. What is the measurement from the parallel line (to datum) to the center line of the root?
