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?

yes but i suck at it

all you do is multiply though :/

so 2 * 2x = 4x + 44 = 8x?
 one year ago

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

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

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

so whats the answer? whats DBC?
 one year ago

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