Question

If ø lies in the second quadrant and tan ø= -5/12
find the value of
2 cos/1-sin ø​

Answer 1

Answer:

-3

Step-by-step explanation:

tan∅=-5/12 = opp/adj

hyp=√12^2+5^2 = √169 = 13

since ∅ lies in second quadrant, cos∅= -12/13

                                                     sin∅=5/13

 2cos∅/1-sin∅= (2x-12/13)/ (1-5/13)

                      = (-24/13)/ (8/13)

                       =-3
