a:b:c=4:5:6

In Delta ABC if a:b:c=3:4:5 then sin A:sin B:sin C is

In Delta ABC, if a:b:c=3:4:5 , then sin A:sin B:sin C =

If in triangle ABC,cot A:cot B:cot C=30:19:16 show that a:b:c=5:6:7

In /_\ABC , if a:b:c=3:5:7 , then cos A+cos B=

If cot A/2: cot B/2: cot C/2 = 3:5:7 . Then show that a:b:c = 6:5:4 (In /_\ABC ).

If cot A/2:cot"" B/2: cot"" C/2 = 3:5:7 then show that a:b:c = 6:5:4 .

(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.

If 2a=3b=4c, then a:b:c=2:3:4(b)3:4:64:3( d) 6:4:3
