    Answer:

    Step-by-step explanation:

    1] 3x + 20° + 4x – 36° = 180° (linear pair)

      7x – 16 ° = 180°

      7x = 180 + 16

      7x = 196

      x = 196 ÷ 7

      therefore x = 28

    2] 5x + 11x + 2x = 180°

    ⇒ 18x = 180°

    ⇒ x = 10°

    3] 3x+7x+2x=180  


    12x=
    180/12  =15

    ∴ Value of {x = 15}
