Stupid stuff like this is why kids hate math class. Unless the problem says calculate all unmarked angles, those visually 90 degree angles are 90 degrees. It works that way in any non engineering job that uses angles because it's common sense.

...what? I get that this drawing is very dysfunctional, but are you going to argue that a triangle within a plane can have a sum of angles of 190°?

The sum of the angles of a triangle are always 180°

Yes, I believe I implied this by suggesting that the sum of angles being 190° is absurd.
