$${F}_{{y}} =\mathrm{7}×\mathrm{10}−\mathrm{30}\sqrt{\mathrm{2}}×\frac{\mathrm{1}}{\sqrt{\mathrm{2}}}=\mathrm{40}\:{N} \\ $$$${F}_{{x}} =\mathrm{30}\sqrt{\mathrm{2}}×\frac{\mathrm{1}}{\sqrt{\mathrm{2}}}=\mathrm{30}\:{N} \\ $$$${F}_{{total}} =\sqrt{\mathrm{40}^{\mathrm{2}} +\mathrm{30}^{\mathrm{2}} }=\mathrm{50}\:{N} \\ $$$$\Rightarrow{answer}\:\left(\mathrm{1}\right) \\ $$
