Answer:
25.33
Step-by-step explanation:
given triangle PQR ~ triangle JKL
the ratio of the lengths of their sides are the same
i.e
[tex]\frac{KL}{QR} =\frac{JK}{PQ} =\frac{JL}{PR}[/tex]
in our case, we are given JL, PR and PQ and we are asked to find JK
hence
JK/PQ = JL/PR (rearranging)
JK = (JL/PR) x PQ
= (28/42) x 38
= 25.33333
= 25.33 (2 dec. pl)
