Which of the following are the angles of a scalene triangle?

Question

Accepted Answer

A scalene triangle is a triangle in which all three sides and all three angles are different. Let's analyze each option:

1. 60°, 30°, and 90°: All angles are different, so this can be a scalene triangle.
2. 110°, 35°, and 35°: Two angles are equal (35° and 35°), so this is an isosceles triangle, not scalene.
3. 60°, 60°, and 60°: All angles are equal, so this is an equilateral triangle.
4. 90°, 45°, and 45°: Two angles are equal (45° and 45°), so this is an isosceles right triangle.

Therefore, only option 1 represents the angles of a scalene triangle.
