    A=B/2……………1

    A=C/6……………..2

    FROM 1 & 2,

    WE GET B/2=C/6

    I.E. B=C/3……………….3

    ALSO WE KNOW THAT A+B+C=180

    PUT A=C/6 AND B=C/3, WE GET

    C/6+C/3+C=180

    I.E. C+2C+6C=1080

    I.E. 9C =1080

    C=120

    PUT IN 2, WE GET A=120/6=20

    PUT IN 3, WE GET B=120/3=40
