If angle C of triangle ABC is `90^0,` then prove that `tanA+tanB=(c^2)/(a b)` (where, `a , b , c ,` are sides opposite to angles `A , B , C ,` respectively).

If angle C of triangle ABC is 90^(@) ,then prove that tan A+tan B=(c^(2))/(ab) (where,a,b,c, are sides opposite to angles A,B,C, respectively).

In DeltaABC if m angle C = 90^@ than tanA + tanB = ......(where a,b,c are sides opposite to angles A, B, C respectively).

In a triangle A B C ,/_C=pi/2dot If tan(A/2)a n dtan(B/2) are the roots of the equation a x^2+b x+c=0,(a!=0), then the value of (a+b)/c (where a , b , c , are sides of opposite to angles A , B , C , respectively) is

In a triangle A B C ,/_C=pi/2dot If tan(A/2) and tan(B/2) are the roots of the equation a x^2+b x+c=0,(a!=0), then the value of (a+b)/c (where a , b , c , are sides of opposite to angles A , B , C , respectively) is
