Answer:
D) JK = 58
Step-by-step explanation:
In a parallelogram, opposite sides are parallel and equal in length.
Therefore, in parallelogram JKLM:
JK ≅ LM
KL ≅ JN
Given that LM = 58, then JK also equals 58, so:
[tex]\LARGE\boxed{\boxed{\overline{JK}=58}}[/tex]
Answer:
58
Step-by-step explanation:
Since the opposite sides of a parallelogram are equal.
So,
KJ = LM
3x - 14 = 58
3x = 58 + 14
3x = 72
x = 72/3
x = 24.
Now
JK = 3 × 24 - 14 = 58
Therefore, the answer is: 58
