5.If `A=(1)/(3)B` and `B=(1)/(2)C`,then `A:B:C=`?

If A=3B = 5C, find A:B:C.

If A:B=3:4 and B:C=2:3 , find A:B:C .

In /_\ABC , if sin A= 1/3 and sin B= 1/4 , sin C=

In a "Delta"A B C , let a ,b , and c denote the length of sides opposite to vertices A, B, and C respectively. If b=2,c=sqrt(3) and /_B A C=pi/6, then value of circumradius of triangle ABC is- 1/2 (2) 1 (3) 2 (4) 1/4

In a triangle ABC , if r_(1) =2r_(2) =3r_(3) , then a:b:c =

If 2A = 5B = 7C, find A:B:C.

In a triangle ABC, angle A = 60^(@) and b : c = (sqrt3 + 1) : 2 , then find the value of (angle B - angle C)

If a statement is true for all the values of the variable, such statements are called as identities. Some basic identities are : (1) (a+b)^(2)=a^(2)+2ab+b^(2)=(a-b)^(2)+4ab (3) a^(2)-b^(2)=(a+b)(a-b) (4) (a+b)^(3)=a^(3)+b^(3)+3ab(a+b) (6) a^(3)+b^(3)=(a+b)^(3)=3ab(a+b)=(a+b) (a^(2)-ab) (8) (a+b+c)^(2)=a^(2)+b^(2)+c^(2)+2ab+2bc+2ca=a^(2)+b^(2)+c^(2)+2abc((1)/(a)+(1)/(b)+(1)/(c)) (10) a^(3)+b^(3)+c^(3)-3abc=(a+b+c)(a^(2)+b^(2)+c^(2)-ab-bc-ca) =1/2(a+b+c)[(a-b)^(2)+(b-c)^(2)+(c-a)^(2)] If a+b+c=0,thena^(3)+b^(3)+c^(3)=3abc If x+(1)/(x)=2, thenx^(2)+(1)/(x^(2)) is equal to

If the points ((a^3)/((a-1))),(((a^2-3))/((a-1))),((b^3)/(b-1)),((b^2-3)/((b-1))) , ((c^3)/(c-1)) and (((c^2-3))/((c-1))), where a , b , c are different from 1, lie on the l x+m y+n=0 , then (a) a+b+c=-m/l (b) a b+b c+c a=n/l (c) a b c=((m+n))/l (d) a b c-(b c+c a+a b)+3(a+b+c)=0

In a triangle ABC , if 1/(b+c)+1/(c+a)=3/(a+b+c) , then angleC =
