$\overrightarrow{BD}$ bisects $\angle ABC$ . Find $m\angle ABD$ , $m\angle CBD$ , and $m\angle ABC$ .
Two rays B A and B C begin from a common point B, to form angle A B C. A ray B D bisects angle A B C. Angle A B D measures left-parenthesis negative 4 x plus 33 right-parenthesis degrees. Angle D B C measures left-parenthesis 2 x plus 81 right-parenthesis degrees.
