Question

a triangle has angle measurements of 99°, 47°, and 34°. what kind of triangle is it?
equilateral
isosceles but not equilateral
scalene

Explanation:

Step1: Recall triangle types

Equilateral: all angles \(60^\circ\). Isosceles: at least two angles equal. Scalene: all angles different.

Step2: Compare given angles

Given angles: \(99^\circ\), \(47^\circ\), \(34^\circ\). All are distinct (no two equal, none \(60^\circ\)).

Answer:

scalene
