help i am stuck on this homework problem i know how to do the formula i just get stuck on how to finish it....
find <ABC

anonymous · Answer

|dw:1380227475640:dw|

anonymous · Answer

whenever two lines like this intersect:

< abc = < dbe

and

< abd = < cbe

this means that

6x - 7 = 4x + 23

solve for x then plug it in.

i know that but this is what i get when i do that  |dw:1380233676187:dw|

anonymous · Answer

that's fine.

this means < abc = 83.

how do u get 83

directrix · Answer

The measure of < ABC is given algebraically as (6x - 7)/

Assuming x = 15, then the measure of <ABC = 6*15 - 7 = ?   @leroysgurl15

gotcha thanks

directrix · Answer

You are welcome. Also, note the reason that those two angles are congruent is that they are vertical angles. By a theorem, vertical angles are congruent and therefore have the same measure.
