\(\tan A=\frac{-60}{11}\) and \(A\) does not lie in the 4th quadrant. \(\sec B=\frac{41}{9}\) and \(B\) does not lie in the 1st quadrant. If \(\operatorname{cosec} A+\cot B=K\), then \(24 K=\)
- A 11
- B 19
- C 40
- D 61
Answer & Solution
Correct Answer
(B) 19
Step-by-step Solution
Detailed explanation
\(\tan A=\frac{-60}{11}, A\) lies in \(2^{\text {nd }}\) quadrant \((\tan A\) is - ve \()\), does not lie in \(4^{\text {th }}\) quadrant. \(\therefore \operatorname{cosec} A=+\frac{61}{60}[A\) lies in 2nd quadrant, \(\operatorname{cosec} A\) is +ve\(]\)…
