  • Jawab :

    7x = 2x + 80
    7x - 2x = 80
    5x = 80
    x = 80/5
    x = 16

    sudut HFE
    = 180° - 7x
    = 180° - 7.16
    = 180° - 112
    = 68°

    7x = 2x + 80°
    7x - 2x = 80°
    5x = 80°
    x = 80°/5
    x = 16°

    sudut HFE

    =180° - 7x
    =180° - 7(16°)
    =180° - 112°
    =68°
