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 //2 if tan (p//2) and tan ( Q//2) are the roots of the equation ax ^2 + bx +c=0 ( a ne 0) then

In a triangle PQR, angleR = pi //2 . If tan (P/2) and tan (Q/2) are the roots of the equations ax^(2) + bx + c = 0 where a ne 0 , then

In trianglePQR, angleR = (pi)/(2) . If tan((P)/(2)) " and " tan ((Q)/(2)) are roots of equation, ax^(2) + bx + c = 0 , then which of the following is true.
