Best ResponseYou've already chosen the best response.1dw:1352609533315:dw line BD is an angle bisector, so both of those angles would be congruent

Best ResponseYou've already chosen the best response.1since angles ABD and DBC are adjacent angles that make up angle ABC, we can say that 2(2x + 22) = 8x

Best ResponseYou've already chosen the best response.0so 2 * 2x = 4x + 44 = 8x?

Best ResponseYou've already chosen the best response.1after distributing, you should get 4x + 44 = 8x, yes.

Best ResponseYou've already chosen the best response.0so then its 44 / 4 = 11 x = 11?

AriPotta

Best ResponseYou've already chosen the best response.1you didn't show that you subtracted 4x from 8x, but yes. x = 11 :)

Best ResponseYou've already chosen the best response.0so whats the answer? whats DBC?

AriPotta

Best ResponseYou've already chosen the best response.1angle DBC = 2x + 22, so just substitute 11 for x in that equation to get your answer
