θ=tan^(−1) (3/5)+tan^(−1) (2/5)  tan θ=(((3/5)+(2/5))/(1−(3/5)×(2/5)))=((25)/(19))
$$\theta=\mathrm{tan}^{−\mathrm{1}} \frac{\mathrm{3}}{\mathrm{5}}+\mathrm{tan}^{−\mathrm{1}} \frac{\mathrm{2}}{\mathrm{5}} \\ $$$$\mathrm{tan}\:\theta=\frac{\frac{\mathrm{3}}{\mathrm{5}}+\frac{\mathrm{2}}{\mathrm{5}}}{\mathrm{1}−\frac{\mathrm{3}}{\mathrm{5}}×\frac{\mathrm{2}}{\mathrm{5}}}=\frac{\mathrm{25}}{\mathrm{19}} \\ $$
