\;A + B + C = \pi \,\,\;\mathrm{and}\,\,\cos \,\,A = \cos \,\,B\,\,\cos \,\,C

then

\tan \,\,B\,\,\tan \,\,C

is equal to

View answer and explanation

Correct option: B

\mathrm{1}

Option B (1) is correct because by using the given condition

A + B + C = \pi

and the trigonometric identity, we can derive that

\tan B \tan C = 1
