In $$\triangle A B C$$ and $$\triangle B C D$$, (8) $$A B=B D$$ (ii) $$A C=B D$$ (iii) $$B C=B C$$ By SSS rule of congruoney, $$\triangle A B C \cong \triangle D C B$$ By corresponding part of congruent triangles, In $$\triangle A B C$$, $$m \angle A B C+m \angle B C A+m \angle B A C=180^{\circ}$$ or $$m \angle B A C=180^{\circ}-39^{\circ}-73^{\circ}$$ or, $$m \angle B A C=180^{\circ}-112^{\circ}$$ or, $$m \angle B A C=68^{\circ}$$ $$x^{0}={R} \angle B D C \neq 1 \angle B A C=68$$ $$x=68$$
