    Sorry, i got cut off there. The whole angle is 8x. ABD is 2x + 22. BD bisects the angle.

    DBC is 2x + 22. A bisector cuts the angle in half. A half + a half = a whole, but there is still TWO parts to it. What can you do using 2?

    2x + 22 = 8x / 2 BD "cuts" ABC in half.

    Multiply both sides by 2. You will end up with this equation:\[2(2x + 22) = 2(\frac{ 8x }{ 2 })\]

    \[8x = (4x + 44) / 4\]\[44 \div 4\]

    Plug x into the equation now. 4(x) + 44

    X is 11, which means that DBC =

    Remember when I said that DBC = 2x + 22? That's right too. DBC = 2(11) + 22 It's a puzzle that requires a little thinking. :)
