Question Analysis:
This question involves classifying triangles based on their angles.
The main focus is on identifying an obtuse triangle, which has one angle greater than 90°.

Key Concept Explanation:
Acute triangle: All angles < 90°.
Right triangle: One angle = 90°.
Obtuse triangle: One angle > 90°.
Equilateral triangle: All angles = 60° (a subtype of acute).

Step-by-Step Solution:
The triangle has one angle = 95° (> 90°).
The other two angles are each < 90°.
Therefore, it is an obtuse triangle.

Option Analysis:
A) Incorrect: Acute triangles have all angles < 90°.
B) Incorrect: Right triangles have one 90° angle.
C) Correct: Matches the ...
