Answer:
Nonverbal and verbal communication work hand in hand. How do the two work together? Well, let's say you're talking with someone. Let's say you have a friend that says, "Hey, I love this song that's playing on the radio!" By agreeing verbally with a, "Yeah, I agree!" along with a nod and smile shows how nonverbal and verbal communication work together.
Another example of how they work together is, though this is a depressing topic - at a funeral. You would say, "Sorry for your loss," but you WOULDN'T be smiling while you say this. Therefore, nonverbal communication used correctly is necessary in situations like this.
In all, the two work together.
