Question

Please tell me B value

Answer 1

Hello Friend
the value of B is 30degrees and tan (75degrees)=root 3+2

Answer 2

⛤HERE IS YOUR ANSWER⛤

$tan(45 + \beta ) = 2 + \sqrt{3} \\ or \: \: \frac{tan45 + tan \beta }{1 - tan45.tan \beta } = 2 + \sqrt{3} \\ or \: \: \frac{1 + tan \beta }{1 - tan \beta } = \frac{2 + \sqrt{3} }{1} \\ operting \: we \: get \\ \frac{(1 + tan \beta ) + (1 - tan \beta )}{(1 + tan \beta ) - (1 - tan \beta )} = \frac{(2 + \sqrt{3} ) + 1}{ (2 + \sqrt{3} ) - 1} \\ or \: \: \frac{2}{2tan \beta } = \frac{3 + \sqrt{3} }{1 + \sqrt{3} } \\ or \: \: \frac{1}{tan \beta } = \frac{ \sqrt{3} (1 + \sqrt{3} )}{1 + \sqrt{3} } \\ or \: \: \frac{1}{tan \beta } = \sqrt{3} \\ or \: \: tan \beta = \frac{1}{ \sqrt{3} } = tan \frac{\pi}{6} \\ or \: \: \beta = \frac{\pi}{6}$
