How do you find unknown angles in a triangle only showing the area?

If you only know the area of a triangle and nothing else, then

you can't calculate any of the angles or any of the sides.

All you know is that half of (the base times the height) is

equal to the area, and that is all.

Each triangle is 180 degeese so if you get one angle take that away from 180 and the half the answer
