    Use the fact that BCD is isocles and all angles in a triangle add up to 180 degrees.

    you can work x out cos its in a isocles traingle-
    so 34 +2x= 180
    rearange this to make x the subject so u get:
    x= 180-34/2
    x=73

    you can work y out cos all angles in triangle =180
    so y+x+34 +38 =180
    x= 73

    so y + 145=180
    therefore y = 35

    soz i dont know the last part

    AD doesn't equal DC becasue 35dgrees doesn't eqaul 38 degrees therefore lines that meet at the same point(D) cannot be of equal length

    hope that hepls
