  • ∠ABD + ∠DBE = 180°
    7x + 11x = 180°
    18x = 180°
    x = 180° / 18
    x = 10°

    ⇔∠ABD
    = 180° - 7x
    = 180° - 7(10°)
    = 180° - 70°
    = 90°

  • Garis dan Sudut

    <ABD + <DBE = 180°
    7X + 11X = 180°
    18X = 180°
    X = 180/18
    X = 10

    Pelurus <ABD = <DBE
    = 11X
    = 11 x 10
    = 110°

    *semoga membantu. sukses selalu ^_^
