\sin \,\,A - \sqrt 6 \,\,\cos \,\,A = \sqrt 7 \,\,\cos \,\,A

, then

\cos \,\,A + \sqrt 6 \,\,\sin \,\,A

is equal to

View answer and explanation

Correct option: B

- \,\sqrt 7 \,\sin \,\,A

Option B (

- \,\sqrt 7 \,\sin \,A

) is correct because it is derived by substituting A with 90° + A in the given equation.
