    Answer:

    1).

    Sqrt (7 x 12) = 9.165

    2).  

    Altitude = Sqrt (14 x 8) = 10.583

    3).  

    If FG is the angle bisector of angle F in triangle DEF,

    DF/EF = DG/EG

    6/EF = 4/9

    EF = 13.5 in long.

    4).  

    In triangle QRS, XY is parallel to SR.  

    SX/XQ = RY/YQ

    3/2x = 4.5/7.5

    9x = 22.5

    x = 2.5

    The length of QS

    = SX + 2x  

    = 3 + 5

    = 8

    did this help sorry if it didnt
