Question

question in △klm, m∠k = 21° and m∠l = 13°. which list has the sides of △klm in order from shortest to longest? answer ○ mk, kl, lm ○ lm, kl, mk ○ lm, mk, kl ○ kl, lm, mk ○ mk, lm, kl ○ kl, mk, lm

Explanation:

Step1: Find angle M

The sum of angles in a triangle is 180°. So, $m\angle M=180-(m\angle K + m\angle L)=180-(21 + 13)=146^{\circ}$.

Step2: Recall angle - side relationship

In a triangle, the side opposite the smallest angle is the shortest and the side opposite the largest angle is the longest. Since $m\angle L

Answer:

MK, LM, KL
