Answer:
[tex]k=\dfrac{l(h-1)}{2h}[/tex]
Step-by-step explanation:
The given equation is :
[tex]h=\dfrac{l}{l-2k}[/tex] ....(1)
We need to find the value of k.
Cross multiplying equation (1)
[tex]h(l-2k)=l\\\\hl-2hk=l\\\\hl-l=2hk\\\\k=\dfrac{l(h-1)}{2h}[/tex]
So, the value of k is equal to [tex]\dfrac{l(h-1)}{2h}[/tex].
