If A:B:C=3:5:7 and C:D=1:5 then A:D is?

If a:b=3:5 and b:c=6:7 ,find a:b:c

(i) If A:B=2:3,B:C=4:5,C:D=6:7 FIND A:D

If a : b=4:5\ a n d\ b : c=2:3, then a : c=\ .................

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

In a A B C , A D is the bisector of /_B A C . If A B=6c m , A C=5c m and B D=3c m , then D C= 11. 3 c m (b) 2. 5 c m (c) 3:5c m (d) None of these

In a Delta ABC , the median AD is perpendicular to AC. If b = 5 and c = 11, then a =

If A B=7. 5 c m\ a n d\ C D=2. 5 c m , construct a segment whose length is equal to (i) A B-C D (ii) 2A B (iii) 3C D (iii) A B+C D (v) 2A B+3C D

If in a /_\ ABC, a=6, b=3 and cos(A-B)= 4/5 then (A) C=pi/4 (B) A=sin^-1 2/sqrt(5) (C) ar(/_\ ABC)=9 (D) none of these

In Figure, if A C is bisector for /_B A D such that A B=3\ c m\ a n d\ A C=5\ c m , then C D= (a) 2\ c m (b) 3\ c m (c) 4\ c m (d) 5\ c m

If a: b= 2: 3, b: c= 4: 5 and c: d= 6: 7 , find : a: b: c:d .
