If the length of JK is 3x and the length of LM is 12x and the length of the entire line JM is 25x , find the length of KL.

Leona [35]

Answer:

10x.

Step-by-step explanation:

It is given that,

JK = 3x

LM = 12x

JM = 25x

Let as consider the line as shown in the below figure.

From the figure it is clear that,

$JK+KL+LM=JM$

$3x+KL+12x=25x$

$KL+15x=25x$

$KL=25x-15x$

$KL=10x$

Therefore, the length of KL is 10x.
