A) 5
B) 13
C) 1
D) 17
Correct Answer: C
Solution :
We have, \[\sqrt{1+\frac{25}{144}}=1+\frac{x}{12}\] \[\Rightarrow \sqrt{\frac{144+25}{144}}=1+\frac{x}{12}\] \[\Rightarrow \sqrt{\frac{169}{144}}=1+\frac{x}{12}\Rightarrow \frac{13}{12}=1+\frac{x}{12}\] \[\Rightarrow \frac{x}{12}=\frac{1}{12}\Rightarrow x=1\]You need to login to perform this action.
