In a ` Delta A B C ,`If `a=18 ,\ b=24 ,\ c=30` , find the value of `cos A ,\ cos B\ a n d\ cos Cdot`

If a=16, b=24 and c=20, then the value of cos(B/2) is

In Delta A B C ,\ if\ a=18 ,\ b=24\ a n d\ c=30\ a n d\ /_C=90^0 find sin A ,\ sin B\ a n d\ sin Cdot

In DeltaABC, a=4, b=6, c=8 , then find the value of 8 cos A + 16 cos B + 4 cos C .

In Delta ABC , angle B = 90^(@) find the values of : sin A cos C + cos A sin C

In Delta ABC if a= 16 , b= 24 and c = 20 then cos B/2

In Delta ABC , angle B = 90^(@) find the values of : cos A cos C -sin A sin C

Let A,B,C be the three angles such that A+B+C=pi , tan A.tan B=2 , then find the value of (cos A cos B)/(cos C)

If an a triangle A B C , b=3 c, a n d C-B=90^0, then find the value of tanB

In a A B C , if a=3,b=5a n dc=7,fin dcos A ,cos Ba n dcos Cdot

In Delta ABC a =5 ,b=3 ,c=7 .Then value of 3 cos C +7 cos B is equal :-
