Did one angel or multiple angels deliver news to Mary?

>And as the **Angels** said, "O Maryam, (Mary) surely Allah has elected you and purified you and has elected you over the women of the worlds. > >**Dr. Ghali** 3:42 >Screening herself off from them. Then We sent to her Our **angel**, ˹Gabriel,˺ appearing before her as a man, perfectly formed. > >**Dr. Mustafa Khattab, the Clear Quran** 19:17 In verse 3:42 is mentioned that *angels* talked to Maryam talked (more than one). But in verse 19:17 it is mentioned that *angle* talked to Maryam (one angle). So can you explain this.
