Best ResponseYou've already chosen the best response.0I get this: tan 75 = tan (150)/2 = 1  cos(theta)/sin (theta) = 1(sqrt(3)/2)/(1/2) = 2 + sqrt (3)

Best ResponseYou've already chosen the best response.4i would use this one \[\huge\rm tan(\color{reD}{a}+\color{blue}{b})=\frac{ \tan \color{red}{a}+ \tan \color{blue}{b} }{ 1tan\color{reD}{a}tan\color{blue}{b} }\] sum formula for tan
