Answer:
Obtuse scalene triangle
Step-by-step explanation:
1. Angles:
- -> Acute triangle: all angles less than 60°
- -> Right triangle: one angle is 90°
- -> Obtuse triangle: one angle is greater than 90°
- Given the information above, we can see that the triangle has one angle that's greater than 90° (129°), so this triangle is obtuse.
2. Sides:
- -> Scalene triangle: all sides have different lengths
- -> Isosceles triangle: two sides have same length
- -> Equilateral triangle: all sides are the same
- Given the information above, we can see that all the sides in the triangle are different, so this triangle is scalene.
Therefore, the answer is an obtuse scalene triangle.
