For drawing purposes

Answer 3

But we have the measure of \(m\angle\)ABC and \(m\angle DBC\)

\(\angle ABC =~2(\angle DBC)\)

Answer 5

so double dbc?

Answer 6

Yes

Answer 7

And set it equal to ABC

Answer 8

okay...

Answer 9

\((6x-10)=2(2x+20)\)

\(6x-10=4x+40\)
Not sure where you got the -4x o.o

Answer 12
