Question

a triangle has angle measurements of 100°, 31°, and 49°. is this triangle scalene? yes no

Explanation:

Step1: Recall scalene triangle definition

A scalene triangle has all three angles of different measures (and all three sides of different lengths, which is related to angle measures via the Law of Sines).

Step2: Check the given angles

The given angles are \(100^\circ\), \(31^\circ\), and \(49^\circ\). All three angles are distinct (no two angles are equal).

Answer:

yes
