The answer is 72, since for the first person, we have 9 choices.  The second choice, we have 8 choices.  Therefore, the answer is 8 times 9, which is 72.

Please help, I’m not sure what the answer is.

Answer:

The answer is 'C'

Step-by-step explanation:

Congruent simply means "the same." When a line divides two parralel lines transversals are created. This means that there are angles on both lines that are similar. To fully understand which angles would be the same, I reccommend researching "transversals" for more information, or asking your teacher about it as it is hard to explain without a proper diagram.
