Answer:
The length of KH is 6 units and OH is 6.3 units.
Step-by-step explanation:
Given the figure with lengths LO=5 and OK=4. we have to find the length of OH and KH.
In ΔLOH
By Pythagoras theorem
→ (1)
In ΔKOH,
→ (2)
In ΔKHL,

Using eq (1) and (2), we get


⇒ 
⇒ 
Put the above value in eq 2, we get
⇒ KH=6 units.
1:B, 2:A, 3:D, 4:A
those are the answers
