Question

determine if the statement is always, sometimes, or never true. a scalene triangle is obtuse. never sometimes always

Explanation:

A scalene triangle has all sides of different lengths. An obtuse triangle has one angle greater than 90 degrees. A scalene triangle can be obtuse (e.g., sides 3, 4, 6: using the Law of Cosines, the largest angle is obtuse), but it can also be acute (e.g., sides 2, 3, 4: all angles less than 90 degrees) or right (e.g., sides 5, 12, 13: right - angled, and scalene as all sides are different). So a scalene triangle is obtuse only sometimes.

Answer:

sometimes
