    Step-by-step explanation:

    RATIO = 2:7

    THEN THE ANGLES ARE = 2x and 7x

    SUPPLEMENTARY ANGLES ADD UPTO 180

    THEN THE EQUATION FORMED IS –

    2x + 7x = 180

    9x = 180

    x = 180/9

    x = 20

    THEN ANGLES ARE –

    2x = 2 X 20 = 40

    7x = 7 X 20 = 140

    THE TWO SUPPLEMENTARY ANGLES ARE 40 AND 140
