$${B}+{D}=\mathrm{180}° \\ $$$$\frac{{B}}{{D}}=\frac{\mathrm{2}}{\mathrm{3}} \\ $$$${B}+\frac{\mathrm{3}}{\mathrm{2}}{B}=\mathrm{180} \\ $$$$\frac{\mathrm{5}}{\mathrm{2}}{B}=\mathrm{180} \\ $$$$\Rightarrow{B}=\frac{\mathrm{360}}{\mathrm{5}}=\mathrm{72} \\ $$$$\angle{AMC}=\mathrm{2}{B}=\mathrm{144}° \\ $$
