Analyze the subject and verb agreement for the first sentence

The subject is "Andrés" (third-person singular, "él"). The present perfect conjugation of "haber" for "él" is "ha". Therefore, the correct verb form is "ha llegado".

Analyze the subject and verb agreement for the second sentence

The subject is "Él" (third-person singular). The present perfect conjugation of "haber" for "él" is "ha". Therefore, the correct verb form is "ha tomado".
