" If "a:b:c=4:5:6," then show that "/_C=2/_" A."

In a Delta ABC, if a:b:c=4:5:6, then the ratio of the radius of its circumcircle to that of its incircle

If A:B:C=4:5:6 , then what is the ratio of (1/A):(1/B):(1/C) ?

In a Delta ABC , if a:b:c=4:5:6 , then the ratio of the radius of the circumcircle to that of the incircle is

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

If a:b=5.6 and b:c=4:7 then a:b:c=

If (5a-3b)/a= (4a+b-2c)/(a+4b-2c) = (a+2b-3c)/(4a-4c) , then show that 6a=4b=3c.

If a:b:c=2:3:4, find a,b and c
