In a triangle PQR angle R=(pi)/(4), if tan (p/3) and tan ((Q)/(3)) are the roots of the equation ax ^2 + bx +c=0 then

In a triangle PQR angle R=(pi)/(4), if tan (p/3) and tan ((Q)/(3)) are the roots of the equation ax ^2 + bx +c=0 then

In any triangle PQR, angleR = pi/2 . If tan 'P/2 and tan 'Q/2 are the roots of the equation ax^(2) + bx + c=0 (a ne 0) , then show that, a+b=c.

In any triangle PQR, angleR = pi/2 . If tan 'P/2 and tan 'Q/2 are the roots of the equation ax^(2) + bx + c=0 (a ne 0) , then show that, a+b=c.

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

In Delta PQR,/_R=(pi)/(4),tan((P)/(3)),tan((Q)/(3)) are the roots of the equation ax^(2)+bx+c=0, then
