`" In a "Delta ABC,b" and "c" satisfy "b^(2)-bc-2c^(2)=0" and "|B-C|=(pi)/(3)" .The measure of "/_A" is "`

In Delta ABC,a=2b and |A-B|=(pi)/(3) then /_C is

In any Delta ABC,sum a(sin B-sin C)=a^(2)+b^(2)+c^(2)(b)a^(2)(c)b^(2)(d)0

In a Delta ABC, c cos ^(2)""(A)/(2) + a cos ^(2) ""(C ) /(2)=(3b)/(2), then a,b,c are in

In Delta ABC,(a+b)(a-b)=c(b+c) then measure of angle A is

In a Delta ABC if a^(2)sin(B-C)+b^(2)sin(C-A)+c^(2)sin(A-B)=0, then triangle is

In Delta ABC , if b^(2) + c^(2) - a^(2) = bc, then angle A = __________.

In a Delta ABC,2B=A+C and b^(2)=ac. Then the value of (a^(2)(a+b+c))/(3abc) is equal to

In a triangle ABC the angle B is greater than angle C. If the measure of angles B and C satisfy the equation 4sin^3x-3sinx+0.75=0 then the measure of angle A is (A) pi/2 (B) (2p)/3 (C) pi/6 (D) (5pi)/6

In a Delta ABC if b+c=2a and /_A=60^(@) then Delta ABC is

If, in Delta ABC, a^(4) + b^(4) + c^(4) = 2a^(2)(b^(2) + c^(2)) then : m/_A = ...
