$$\left(\mathrm{3}{x}−\mathrm{3}\right)+\left(\mathrm{6}{x}+\mathrm{10}\right)+\left(\mathrm{2}{x}−\mathrm{4}\right)+\left(\mathrm{4}{x}−\mathrm{18}\right)=\mathrm{360} \\ $$$$\mathrm{15}{x}−\mathrm{15}=\mathrm{360} \\ $$$${x}=\frac{\mathrm{360}+\mathrm{15}}{\mathrm{15}}=\frac{\mathrm{375}}{\mathrm{15}}=\mathrm{25}° \\ $$
