Trigonometric Identities Question 125

Question: If $ \text{cosec }A+\cot A=\frac{11}{2}, $ then $ \tan A= $

[Roorkee 1995]

Options:

A) $ \frac{21}{22} $

B) $ \frac{15}{16} $

C) $ \frac{44}{117} $

D) $ \frac{117}{43} $

Show Answer

Answer:

Correct Answer: C

Solution:

$ cosec,A+\cot A=\frac{11}{2}\Rightarrow cosec,A-\cot A=\frac{2}{11} $ Therefore $ 2\cot A=\frac{117}{22}\Rightarrow \tan A=\frac{44}{117} $ .
