Answer:
When addressing an unknown audience in a cover letter, a writer should adopt a professional and formal tone. This means using clear, concise, and grammatically correct language, avoiding slang or colloquialisms, and maintaining a respectful and courteous tone. The writer should also avoid being too casual or overly familiar, as this can come across as unprofessional. Additionally, it's important to tailor the tone of the cover letter to the specific industry or company to which it is being submitted. Researching the company's values and culture can help the writer strike the right tone and make a positive impression on the reader.
