Question

jl = 74. find the value of x.
j x k 57 l

Explanation:

Step1: Identify segment - addition postulate

By the segment - addition postulate, $JL=JK + KL$.

Step2: Substitute given values

We know that $JL = 74$, $JK=x$, and $KL = 57$. So, $74=x + 57$.

Step3: Solve for x

Subtract 57 from both sides: $x=74 - 57$.
$x = 17$

Answer:

$17$
