if

6cot teta+2 cosec teta =cot teta+ 5cosec teta

then cos teta=

  1. 4/5
  2. 3/5
  3. 5/3
  4. 5/4

6cot theta + 2cosec theta = cot theta + 5cosec theta 6cot theta - cot theta= 5cosec theta - 2cosec theta 5cot theta= 3cosec theta Cot theta=cos theta\sin theta and cosec theta =1\sin theta 5cos theta\sin theta= 3\sin theta 5cos theta = 3 Cos theta =3\5 Therefore option c) is correct
