How the two words are related
Same Semitic root, same meaning — you already know this word.
Arabic root
ث-ل-ثHebrew root
ש-ל-שBoth languages make the tens by pluralizing the unit: Hebrew שלוש takes ־ים to give שלושים, Arabic thalāth takes ـُون to give thalāthūn — parallel masculine-plural endings tacked onto the same root, just as with 'twenty'.

How people actually say it in the spoken dialects, where it differs from the standard word.
Levantine · Palestine, Jordan, Lebanon, Syria
Spoken Arabic uses the oblique -īn form (and the dialectal t for ث), just like ʿishrīn for twenty.
Egyptian · Cairo and the Nile Delta
Cairene shortens the unstressed ā: talatīn, tamanīn.
Moroccan · Morocco — Casablanca, Rabat, Fes
The tens keep the -īn ending; only the opening consonant cluster is Moroccan.
