" a "/_ABC," two sides are "a=3,b=5" and "cos(A-B)=(7)/(25)," find "tan

In a triangle ABC, two sides are a = 6, b = 3 and cos(A-B) =(4)/(5) then the area of the triangle is

If in a /_ABC,a=6,b=3 and cos(A-B)=(4)/(5) then find its area.

In any triangle ABC, the side are a=7,b=5 and c=8. Find A.

In Delta ABC , if the sides are a = 3, b = 5 and c = 4 , then sin . B/2 + cos . B/2 is equal to

(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.

Inf Delta ABC, if a=25,b=52 and c=63 find cos A

Evaluate: tan{cos^(-1)(-7/(25))}

If A+B, A are acute angles such that sin (A+B)=(24)/(25) and tan A=(3)/(4) , then find the value of cos B .

If the sides of a triangle are 3,5 and 7, then find cos A
