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

start from the top

like the beginning

this angle = 8x

i need to be able to type how i got everything like a explanation

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

thats the answer?

no

what do you get after distributing the 2?

ummmm

you know about the distributive property, yes?

yes but i suck at it

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?

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?

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

oh thank you so much!!!

no problem :)

so DBC is 44?

yes
