Dercksen hammered 104 off 84 balls (nine fours, six sixes) and Tryon 74 from 51 (four fours, five sixes) as South Africa piled on 315-9.
Dewmi Vihanga was the standout bowler for the hosts, picking up a career-best 5-43.
In reply, Sri Lanka were bowled out for 239 in the 43rd over, despite a fighting 52 off 57 balls from captain Chamari Athapaththu.
Tryon starred with the ball too, bagging her first ODI five-for with figures of 5-34, including a stunning hat-trick.
In doing so, she reached the milestone of 50 ODI wickets and became only the third Proteas Women player to claim a hat-trick in ODI cricket after Masabata Klaas and Dané van Niekerk.
Sri Lanka will now take on India in the Tri-Series final on Sunday.
