The answer is 20 but I have no idea how they got it.

Yes this is all that they gave for information. I was thinking that they left out something as well. Is it plausible just to answer the question with only the angles?

You can't answer the question with only the angles, because every angle on every equilateral triangle is 60 degrees (d'uh!).
You can find the length of the sides if they give you either the area or the perimeter.
