If angles A and B of `Delta ABC (A != B)` are the roots of equation `cos3x = 1/3,` then the angle C c can be

If the sines of the angles A and B of a triangle ABC satisfy the equation c^2x^2-c(a+b)x+a b=0 , then the triangle (a) is acute angled (b) is right angled (c) is obtuse angled (d) satisfies the equation sinA+cosA ((a+b))/c

If the sines of the angles A and B of a triangle ABC satisfy the equation c^2x^2-c(a+b)x+a b=0 , then the triangle (a) is acute angled (b) is right angled (c) is obtuse angled (d) satisfies the equation sinA+cosA ((a+b))/c

The angles A, B and C of a triangle ABC are in arithmetic progression. If 2b^(2)=3c^(2) then the angle A is :

The angles A, B and C of a triangle ABC are in arithmetic progression. If 2b^(2)=3c^(2) then the angle A is :

The angles A,B and C of a triangle ABC are in A.P. If b:c=sqrt(3):sqrt(2) , then the angle A is

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

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

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

In a triangle ABC , if angle A=60 , a=5,b=4 then c is a root of the equation
