The component of a formal letter that should include the sender's address, date, and recipient's address is the Header.

The header is the section at the beginning of a formal letter that typically contains all the necessary information about the sender and the recipient. It usually follows this format:

1. Sender's Address: This is the address of the person sending the letter.
2. Date: This indicates when the letter is being sent.
3. Recipient's Address: This is the address of the person or organization receiving the letter.

Including these elements in the header ensures that the recipient has the necessary information about who is writing and when the correspondence took place, which is important for clarity and record-keeping.
