How to recognise the immediate constituents ?

Dear teachers,

Would you please help me find the constituents of the following sentences ?

1) Thirty major corporations had made billions of dollars in profits

thirty...corporations = subject
had made = verb
billions of dollars in profits = complement
OR
billions of dollars = complement
in profits = ???

2) Twenty-six of the 30 companies continued to enjoynegative federal income tax rates.
twenty...companies = subject
continued to enjoy = transitive verb ?
negatjve...rates = direct object

What are the parts of speech of "continued to enjoy", please?

Thank you for your help.

What are the parts of speech of "continued to enjoy", please?
continued - a verb
to - a particle
enjoy - a verb


In the sentence "Twenty-six
of the 30 companies continued to enjoy negative federal income tax rates"

continued is the predicate and to enjoy is the object of the verb.

As to "in profits", I suppose it is an adverbial modifier of place.
