    Am I stupid or is one triangle unnecessary?

      It is necessary. In the left triangle, the angle that is shown to be right is actually 80°, since other angles are 60 and 40, totaling 100.

          that’s on purpose. it checks whether you actually verify information out just make assumptions. you’re not supposed to eyeball things.
