Question

v If A lies in second quadrant and tanA=-5/12 then value of 2cosA/1- sin A is
​

Answer 1

Answer:

- 3

Step-by-step explanation:

If tan A = - 5/12 then ,

cos A = - 12/13 [As A lies in 2nd quadrant]

sin A = 5/13

Therefore ,

2cos A/1 - sin A

=> 2 (- 12/13)/1 - 5/13

=> - 24/13 × 13/8

=> - 3
