    PF/QB=CP/CQ
    1,8/QB=3/7+3=3/10
    QB=1,8/10
    =6 CM

    CARI A, B
    AB= AQ + QB
    =8+6
    =14 CM

    CARI ABD
    D6/DB=FG/AB
    =8/8+X=4/7
    4(4 + X) =8 X 7
    =32+4 X =56
    4 X=56-32=24
    X=24/4=6 CM

    CARI BCD

    B6/BD=EG/CD
    =X/X+8 = Y/14
    6/6+8=4/14
    14Y =6 X 14
    Y=6 X 14/14=6 CM

    ΔABD
    AB/X=BD/DD
    10/X=(2+3)/2
    X(2+3)=10 X2=20
    5 X 20=20/5=4 CM

    ΔADC
    DC/(PQ+X)=AC/AQ
    20/PQ+4 =3+2/3
    =5CPQ+4)20 X 3
    PQ +4 60/5
    =12
    =12-4=8 CM
