    2(2x + 22) = 8x

    hhow would u figure all that out mathematically can you show me how to do it

    you would distribute the 2 into the parentheses first

    |dw:1352609533315:dw| line BD is an angle bisector, so both of those angles would be congruent

    since angles ABD and DBC are adjacent angles that make up angle ABC, we can say that 2(2x + 22) = 8x

    what do you get after distributing the 2?

    all you do is multiply though :/

    so 2 * 2x = 4x + 44 = 8x?

    after distributing, you should get 4x + 44 = 8x, yes.

    now what do you do?

  21. Hbadgerdontcare

    so then its 44 / 4 = 11 x = 11?

    you didn't show that you subtracted 4x from 8x, but yes. x = 11 :)

    so whats the answer? whats DBC?

  24. AriPotta

    angle DBC = 2x + 22, so just substitute 11 for x in that equation to get your answer
