    m\widehat{BC}:m\widehat{BA}:m\widehat{AC}=2:4:6

    2x+4x+6x=360

    12x=360

    x=30

    m\widehat{BA}=4x=4(30)=120^{\circ}

    m\angle AOD=\frac{1}{2}(100+80)=90^{\circ}

    10x-30=7x

    3x=30

    x=10

    AP=7(10)=70

    x=\sqrt{45}\approx 6.7

    4(y+4)=2(14)

    y+4=7

    y=3
