K is between J and L.
So we can write JK + KL = JL
As given JK = 6x , KL = 3x and JL = 27
[tex]6x + 3x = 27[/tex]
Now we can combine 6x and 3x.
[tex]9x = 27[/tex]
On dividing both sides by 9.
[tex] \frac{9x}{9} = \frac{27}{9} [/tex]
[tex]x = 3[/tex].
So the value of JK = 6*3 = 18
value of KL = 3*3 = 9
