$if \: a + b + c = \pi \\ tan(a + b + c) = 0 \\ tan \: a + tan \: b + tan \: c = \\ tan \: a \: tan \: b \: tan \: c \\ as \: c \: is \: obtuse \: so \: tan \: c \: is \: - ve \\ tan \: a + tan \: b + - tan \: c = \\ - tan \: a \: tan \: b \: tan \: c \\ tan \: a \: tan \: b = \frac{tan \: c - tan \: a - tan \: b}{tanc}$

vishalkumar2806: sperate kro or c= pi-(a+b) put kro

rakhithakur: han aay gayaa but one doubt hai ki tan a + tan b +tan c= tan a . tan b. tanc kaise hua

vishalkumar2806: quadrant badlo or - se - cancel kro

rakhithakur: are haan yaar

vishalkumar2806: hogya ye

rakhithakur: but at last i want to tell you thanks

rakhithakur: yes

vishalkumar2806: Isko ques me post kr do m sol dal duga

vishalkumar2806: Tan wale doubt ko
