Question

∆abc me ,(s-a):(s-b):(s-c)=11:9:5 find the ratio of a:b:c​

Answer 1

Step-by-step explanation:

S-a=11. S=a+11=b+8=c+7

Or 3s = a+b+c+26……..1

2s= a+b+c………2

Subtracting 2. From 1

S=26

a= s-11= 26-11= 15

b=s-8= 26-8= 18

C=s-7=26-7=19

a: b:c =15:18:19

Answer 2

Answer:

14:16:20

Step-by-step explanation:

S-a=11. S=a+11=b+9=c+5

Or 3s = a+b+c+25……..1

2s= a+b+c………2

Subtracting 2. From 1

S=25

a= s-11= 25-11= 14

b=s-8= 25-9= 16

C=s-7=25-5=20

a: b:c =14:16:20
