The triangle described in the question is correctly identified as obtuse. An obtuse triangle is defined specifically as a triangle that has one angle measuring greater than 90 degrees. This characteristic sets it apart from other types of triangles.

In contrast, an acute triangle contains all angles less than 90 degrees, while a right triangle has one angle exactly equal to 90 degrees. A scalene triangle, on the other hand, is defined by having no sides of equal length; it doesn’t necessarily relate to the measurements of its angles. Thus, the defining feature of having one angle greater than 90 degrees clearly classifies this triangle as an obtuse triangle.
