ln Delta ABC," if "ac=3,bc=4" and "cos(A-B)=(3)/(4)," then "

In Delta ABC , If a =4 , b=3 and COS(A-B) =3/4, then

In Delta ABC , If a =4 , b=3 and COS(A-B) =3/4, then

In Delta ABC , if a= 2, b= 3 , c=4 then cos A =

In Delta ABC , a= 6 ,b=3 and cos (A-B) = 4/5 .Then are of triangle is

(i) If a:b:c= 2:3:4 and s=27 inches, find the area of the triangle ABC. (ii) If in a triangle ABC, a=6, b=3 and cos(A-B) =4/5 then find its area.

In Delta ABC , if A= (1,2) ,B= (3,4) and AC = 3, BC= 4 , then the equation of altitude through the vertex 'C' is

In Delta ABC, if cos^2 A+ cos^2 B+cos^2 C=3//4 , then the triangle is
