Answer:
ikj
Step-by-step explanation:
In a triangle:
When labeling angles and sides of triangles, it is convention to label the side opposite an angle with the same letter but in lower case.
Therefore in ∆JLK:
As 16 < 73 < 91
⇒ m∠I < m∠K < m∠J
As the angles of ∆JLK in order from smallest to largest are IKJ, then the sides of ∆JLK in order from smallest to largest are ikj.
