In any triangle ABC, if `a : b : c=2 : 3 : 4`, then `R : r=`

Statement-1: In any !ABC , if a : b : c = 4 : 5 : 6, then R:r=16:17. Statement-2: In any !ABC,R/r=(abc)/(4s)

Statement-1: In any !ABC , if a : b : c = 4 : 5 : 6, then R:r=16:17. Statement-2: In any !ABC,R/r=(abc)/(4s)

In a triangle ABC, if a:b:C=3:7:8, then R:r is equal to

In a triangle ABC if sides a = 13, b =14 and c = 15, then reciprocals of r_(1),r_(2),r_(3) are in the ratio

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

In a triangle ABC, if r_1 + r_3 + r = r_2 , then find the value of (sec^2 A + cos^2 B-cot^2 C) ,

In a triangle ABC, if r_1 + r_3 + r = r_2 , then find the value of (sec^2 A + csc^2 B-cot^2 C) ,
