Answer 1

Answer:

Not a triangle

Step-by-step explanation:

In order for a shape to qualify as a triangle, the interior angles must add up to 180°

These angles only add up to 56°, therefore it is not a triangle.

Answer 2

Answer:

obtuse

Step-by-step explanation:

You have an isosceles triangle. 2 of the sides are equal in length. Since, the third side is longer than than the other 2, it will form an obtuse angle. If the third side was shorter, you would have all acute angles.
