isosceles obtuse
scalene right
equilateral
scalene acute

Explanation:

Step1: Check side - length equality

The side - lengths are 5.91, 5.93, and 7.59. Since all three side - lengths are different, the triangle is scalene.

Step2: Check angle measures

The angles are 30°, 50°, and 80°. Since all angles are less than 90° (acute angles), the triangle is acute.

Answer:

Scalene Acute
