calculation intersection lines

[Error404]

hello to everyone, as a good ignorant at school I never followed a lesson. Now I am with a gap that I absolutely want to fill.
When I find myself making holes with the program and I want to quote the total depth (including the tip) I should remove during the function the length of the tip. I use mainly inventor and automatically marks an inclination of 118 degrees. How do I calculate the height of the tip, that is the intersection point of the two straights that appear in my drawing?

if the tip is 118°, with 31° x hole radius.
