Geometry help? Need 20 characters.?
I have a question on my geometry homework that we didn't go over on the lesson:
Ray BD bisects angle ABC. The measure of angle ABD is represented by 4x-4 and the measure of angle ABC is represented by 7x+4. Find the measures of angle DBC.
How would I solve this? Thanks! :)
Also, how would I solve for x given this information? I tried it, and I got 7x+4=7x-4, which is incorrect. Gah!

measure of DBC is ABC minus ABD
so
measure DBC = (7x - 4) - (4x - 4)
you can collect like terms and simplify
