Answer:
Step-by-step explanation:
If BD is altitude then AC is the base.
<u>The length of AC is:</u>
- AC =  
<u>The length of BD is:</u>
- BD =  
<u>The area is:</u>
- A = 1/2bh
- A = 1/2 *  = 18 unit² = 18 unit²
 
        
                    
             
        
        
        
To solve the given equation, w need to review some rules:

The given equation is :


  ⇒⇒⇒⇒ rule (2)

  ⇒⇒⇒⇒ rule (1) and rule (2)

          ⇒⇒⇒⇒ rule (3)
removing the nature logarithm from both sides

∴ x = 4
So, the correct answer is option (2) ⇒⇒⇒⇒ x = 4
