In a triangle ABC the sides b and c are the roots of the equation `x^2-61x+820=0 and A=tan^-1(4/3) then a^2+3` is equal to

If in a !ABC , tan A/2 and tan B/2 are the roots of the equation 6x^(2)-5x+1=0 , then

In a triangle ABC, a= 4, b = 3, angleA= 60° . Then, c is the root of the equation

Let a,b and c be the three sides of a triangle. Suppose a and b are the roots of the equation x^(2)-(c+4)x+4(c+2)=0 and the largest angle of the triangle is

In a Delta ABC, ifsin Aandsin B are the roots of the equation c^(2)x^(2)-c(a+b)x+ab=0 then find /_C .

In a triangle ABC a= 4 , b= 3 , angle A =60 ^@ ,Then c is root of equation :-

If in a triangle ABC a,b,are roots of the equation x^(3)-11x^(2)+38x-40=0 then sum(cos A)/(a) equal to:

If A, B, C are the angles of triangle ABC and tan A, tan B, tan C are the roots of the equation x^(4)-3x^(3)+3x^(2)+2x+5=0 , if the fourth root of the equation is tan D then find 3tan D .
