in which sentences legal used as adjective ?

He is a legal resident of united state-it is legal to wear green on march 7th--he didn’t know that jaywalking was not legal--it’s not legal to jaywalk-find a adjective.
my answer = He is a legal resident of united state-because it says a legal resident

Agree

thanks

Welcome

... because "legal" is describing the noun "resident."

You are correct! In the sentence "He is a legal resident of the United States," the word "legal" is used as an adjective. "Legal" describes the type of resident he is, indicating that his residency is authorized and within the bounds of the law.
