Thanks for the clarifications.

After reading the answers, I was thinking that I can quickly figure out
the
one that I need to contact by finding the reciprocal of my heading in the
different ranges.

Say I am flying 090, the reciprocal will be 270 which would be 119.9

Would that work in all cases? Or are there odd shaped approch regions?

That will only work if you are heading directly towards the airport.
