2)sides be a,a,b
area=(1/2)(a)(asin120)=√3/4 a2
a/sin30=b/sin120
s=a+(b/2)
and (raduis of incircle)=area/s
use them...get the ans
1) r1=s.tan(A/2)
r2=s.tan(B/2)
r3=s.tan(C/2)
tan(A/2) :tan(B/2):tan(C/2)=6:3:2
tanA/2=6k
tanB/2=3k
tanC/2=2k
now in triangle ABC
wer A+B+C=180
tanA/2 .tanB/2 +tanB/2 .tanC/2+tanC/2 .tanA/2=1
