You can tell because of the measurements of the sides and angles.
A scalene triangle is a triangle that has unequal sides. In addition, it also has unequal angles. The measurements given of the sides and the angles are not equal so we can assume that the triangle is scalene.
The question is asking to state the type of a triangle that is describe in the problem if a triangle has 44mm, 28mm, 24mm and an angles of 110, 40, 30, base on the given data, I would say that its a Scalene Triangle. I hope you are satisfied with my answer and feel free to ask for more
