Explanation

To solve the problem, we need to break down the relationships step by step.

1. **Identify the components of the statement**:
- Rita mentions "the girl I met yesterday at the beach."
- This girl is described as "the youngest daughter of the brother-in-law of my friend's mother."

2. **Understand the relationship of "my friend's mother"**:
- Let's denote Rita's friend as "Friend."
- The "mother of Friend" is simply Friend's mother.

3. **Identify the "brother-in-law of my friend's mother"**:
- The brother-in-law of Friend's mother could either be:
- The brother of Friend's father (if the mother has a brother).
- The husband of Friend's mother’s sister (if the mother has a sister).
- In either case, this brother-in-law is a male relative of Friend's mother.

4. **Determine the "youngest daughter of the brother-in-law"**:
- The youngest daughter of this brother-in-law is his daughter.
- This means the girl Rita met is the daughter of Friend's mother's brother-in-law.

5. **Establish the relationship of the girl to Rita's friend**:
- Since the girl is the daughter of Friend's mother's brother-in-law, she is a cousin to Friend.
- This is because the daughter of a parent's sibling (brother-in-law) is a cousin.

6. **Conclusion**:
- Therefore, the girl is related to Rita's friend as a cousin.

Final answer: The girl is the cousin of Rita's friend.
