Respuesta :

Zero.

The sum of these angles is 200°. The sum of angles in a triangle must be 180°. These angles cannot be used to form a triangle.

Answer:

None

Step-by-step explanation:

The angles inside a triangle add to 180. If the angles are 80, 80 and 40, then they must add to 180 to form a triangle.

80+80+40 = 200

This can't be a triangle.
