Answer:
A) m<L, m<K, m<J
Explanation:
Triangle Congruence--
This means that the longest angle is always opposite the longest side,
and vice verse the shortest angle is always opposite the shortest side.
So in triangle JKL, the longest side is line KL (21). This means angle J, which is opposite KL is the longest. Furthermore, angle L, opposite line JK (13), is the smallest. This also concludes angle K is in the middle of the two, forming the sequence L, K, and then J (ascending order).
