(a) tan A+tan B+tan C=tan A tan B tan C

In /_ABC, if tan A:tan B:tan C=1:2:3, then sin A:sin B:sin C=?

If A,B,C are the angles of a triangle and tan A=1,tan B=2, prove that tan C=3 If a,b,c are the corresponding sides,then prove that (a)/(sqrt(5))=(b)/(2sqrt(2))=(c)/(3)

If tan A+tan B+tan C=tan A . tan B . tan then

If A + B + C = pi , prove that tan A+ tan B + tan C = tan A tan B tan C

If A+B+C= pi , prove that tan A+tan B+tan C= tanA tan B tan C

Given that A = B +C. prove that tan A - tan B - tan C = tan A tan B tan C.

If A + B + C =180^@ , prove that : tan A + tan B + tan C = tan A tan B tan C .

If A + B + C = 180^(@) , then prove that tan A + tan B + tan C = tan A tan B tan C.

If A + B + C = 180^(@) , then prove that tan A + tan B + tan C = tan A tan B tan C.
