Answer: A. 7
Step-by-step explanation:
Given : Point S lies between points R and T and RS=6n, ST=35 and RS=42.
Since , RS = 6n and RS = 42
It means
[tex]6n =42[/tex] [By property of equality]
To find the value of n , we divide both sides by 6 , we get
[tex]n=7[/tex]
Therefore , the value of n is 7.
Hence , the correct option is A. 7.
