Hello Bridgett

"Co-terminal" just means it shares the same terminal side of the angle. In other words, it is equivalent.

Now, to get you started, think about these similar examples:

(1) `-10^"o"` is equivalent to `350^"o"`.

(2) `-60^"o"` is equivalent to `300^"o"`.

Draw them if you can't see it.

Do you think you can answer your question now?

So it just means `360-205=155^"o"`? Why do they have to make it sound so complicated?

Your answer is correct.

Mathematics (tries to be) is an exact science, and precision of language is important. But I agree, too many things are made to sound too complicated!
