In a friendly letter, your closing should contain which of the following? Select all that apply. sender's formal title

sender's signature

Explanation:

The point of a friendly letter is to be loose and informal, rather than stiff and formal. You would probably send a friendly letter to friends or close relatives instead of professors and bosses. You wouldn't want to be formal or professional. It should be easy and simple; therefore you just write your signature to let the receiver know who wrote the letter in a friendly way.
