If A +C- B then tan A. tan B. tan C(a) tan A + tan B +tan C(c) tan A + – InterviewSolution

1.	If A +C- B then tan A. tan B. tan C(a) tan A + tan B +tan C(c) tan A + tan B - tan C(b) tan B -tan C-tan A(d) -(tan A +tan B+ tan C)
Answer» Take tan both sidesTan (a+c) = tan b(tan a+tan c) /(1-tana tanc) =tanbtana +tanc =tanb - tan a tanb tancThentana tanb tanc =tanb - tana - tanc
