Quizplus · Accepted Answer

The triangle has different side lengths, making it scalene. Additionally, all of the angles appear to be less than 90 degrees, indicating that it is acute. Therefore, the correct choice is C) Scalene and acute. The triangle has three different side lengths, so it is scalene. Additionally, all angles are acute (less than 90 degrees), so it is acute. The triangle cannot be isosceles because no two sides are equal in length. It also cannot be obtuse because none of the angles measure greater than 90 degrees.
