Halo Mrandydf… jangan sedih 🙁

Itu adjective (angry) + preposition (at/with) bukan verb + preposition. Coba lihat: https://www.wordsmile.com/contoh-kalimat-adjective-diikuti-preposition. Memang ada angry + at dan angry + with. Untuk tau penggunaannya (diikuti apa) kita bisa cek kamus, Mrandydf. Sebagian adjective memiliki “pasangan” preposition yang bisa mengikutinya, tapi setau saya, tidak ada pola khususnya. Jadi kita hanya perlu menemukan dan mengingatnya (coba dimulai dari yang umum digunakan).

angry (adjective)

having strong feelings about something that you dislike very much or about an unfair situation
…
angry with/at somebody: Please don’t be angry with me. It wasn’t my fault.
angry with/at somebody about/for something: I was very angry with myself for making such a stupid mistake.
She felt angry with herself.
angry at/about/over something: I was so angry at the way I had been treated. https://www.oxfordlearnersdictionaries.com/definition/english/angry

Semoga membantu Mrandydf 🙂
