Let ABCD is a quadrilateral such that `A+B=pi,` if `tan A+tan B+tan C+tan D=M,` then `2M` is

If ABCD is a quadrilateral then tan((A+B)/(4))

If A+C=B , then tan A tan B tan C = ?

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

If ABCD is a cyclic quadrilateral, then tan A +tan C =_________.

If ABCD is a cyclic quadrilateral such that 12 tan A-5=0 and 5cos B+3=0 then the quadratic equation whose roots are cos C and tan D is

underset tan If A+tan B+tan C=tan A tan B tan C

If A+B+C=pi , then, find tan A + tan B + tan C

If A+b+C=pi then tan A+tan B+tan Ctan Adot anB tan C
