Question

△abc≅△klj. what is jk? millimeters

Explanation:

Step1: Recall property of congruent triangles

Corresponding sides of congruent triangles are equal. Since $\triangle ABC\cong\triangle KLJ$, side $AB$ corresponds to side $KJ$, side $BC$ corresponds to side $LJ$, and side $AC$ corresponds to side $KL$.

Step2: Identify corresponding sides

We want to find $JK$. The side in $\triangle ABC$ that corresponds to $JK$ is $AB$.

Step3: Determine length of $JK$

The length of $AB$ is $50$ mm, so the length of $JK$ is also $50$ mm.

Answer:

$50$
