Answer 1

Answer:

Answer is A = 20, 40, 120

Step-by-step explanation:

C = 3B, 3B = 2 (A+B)

Using equation

3B = 2 (A + B)

⇒ 3B = 2A + 2B

⇒ 3B - 2B = 2A

⇒  B = 2A

⇒ 3B = 6A

So C = 6A

Now A = C/6 , B = C/3

Also A + B +C = 180                                                (triangle sum law)

So using above relationship

C/6 + C/3 + C = 180

9C/6 =180

C = 180 ×6/ 9

C = 120

∴ A = C/6 =20 , B = C/3 =40

Thats it
