She pulled the door open.
Literal
She [topic-は] door [object-を] pull-and opened.
引いて開けた pairs 引く ('pull') with 開ける ('open') — the standard 'pull-to-open' motion. The te-form here marks the means: 'opened by pulling.' 開ける is the transitive ('open X'); the intransitive 開く describes a door opening on its own — useful when a sliding door, automatic door, or someone else's hand is at work. The 開く / 開ける split is one of Japanese's textbook transitivity pairs. Many traditional Japanese doors slide rather than swing, so the choice of 引く vs 押す (push) often matters less than for hinged Western doors.
