Question

9 ordering 1 point order the sides from least to greatest m n 78° 48° l least 1 mn 2 ln 3 ml greatest previous

Explanation:

Step1: Find the measure of angle \( L \)

The sum of angles in a triangle is \( 180^{\circ} \). So, \( \angle L=180^{\circ}-(78^{\circ} + 48^{\circ})=180^{\circ}-126^{\circ} = 54^{\circ} \)

Step2: Recall the side - angle relationship in a triangle

In a triangle, the side opposite the smaller angle is shorter.
Since \( 48^{\circ}<54^{\circ}<78^{\circ} \), the sides opposite these angles:
The side opposite \( 48^{\circ}\) is \( ML \), the side opposite \( 54^{\circ}\) is \( MN \), and the side opposite \( 78^{\circ}\) is \( LN \)

Answer:

1. \( ML \)
2. \( MN \)
3. \( LN \)
