(B) આપેલ છે કે $	an \alpha = \frac{m}{m + 1}$ અને $	an \beta = \frac{1}{2m + 1}$.સૂત્ર $	an(\alpha + \beta) = \frac{	an \alpha + 	an \beta}{1 - 	an \alpha 	an \beta}$ નો ઉપયોગ કરતા:$	an(\alpha + \beta) = \frac{\frac{m}{m + 1} + \frac{1}{2m + 1}}{1 - \left(\frac{m}{m + 1}ight) \left(\frac{1}{2m + 1}ight)}$$= \frac{\frac{m(2m + 1) + (m + 1)}{(m + 1)(2m + 1)}}{\frac{(m + 1)(2m + 1) - m}{(m + 1)(2m + 1)}}$$= \frac{2m^2 + m + m + 1}{2m^2 + m + 2m + 1 - m}$$= \frac{2m^2 + 2m + 1}{2m^2 + 2m + 1} = 1$તેથી,$	an(\alpha + \beta) = 1$ હોવાથી,$\alpha + \beta = \frac{\pi}{4}$ મળે.

જો $\tan \alpha = \frac{m}{m + 1}$ અને $\tan \beta = \frac{1}{2m + 1}$ હોય,તો $\alpha + \beta = $
