    my guess is you are supposed to use the addition angle formula writing \(105=60+45\)

    \[\tan(60+45)=\frac{\tan(60)+\tan(45)}{1-\tan(60)\tan(45)}\] if i remember that formula correctly

    (tan60+tan45)/(1-tan60 tan45) (radical3+1)/(1-radical3*1) (radical3+1)/(radical3-1) (radical3+1)^2/ (radical3-1) (radical3+1) (4+2radical3)(3-1) (2+radical3) = -3.732050807568877293527446341507
