Answer:
obtuse
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.

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