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

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

In a DeltaABC , if a = 4, b = 3 and angleA=60^(@) , then c is a root of the equation

In a triangle ABC,a=4,b=3,/_A=60^(@) then c is root of the equation c^(2)-3c-7=0 (b) c^(2)+3c+7=0(c)c^(2)-3c+7=0(d)c^(2)+3c-7=0

If in DeltaABC , a = 4,b=3, A = 60^(@) then c is a root of the equation .

In a triangle ABC, if a = 2, b = 3 and c=4 , then cos A is equal to

In triangle ABC , AB = BC , angle B = 40 ^(@) Then angleA is 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 .

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
