Question

k is between j and l, kl = 42, and jl = 47. find jk.

Explanation:

Step1: Recall segment addition postulate

If \( K \) is between \( J \) and \( L \), then \( JK + KL = JL \).

Step2: Substitute known values

We know \( KL = 42 \) and \( JL = 47 \). Substitute these into the equation: \( JK + 42 = 47 \).

Step3: Solve for \( JK \)

Subtract 42 from both sides: \( JK = 47 - 42 \).
Calculate \( 47 - 42 = 5 \).
