  tan 66°+tan 12°=(√3) +tan x  ⇒2.246 + 0.213=(√(3 ))+tan x  ⇒tan x =2.246+0.213−(√3)  ⇒tan x = 0.727  ⇒tan x =tan 36^o   ∴ x=36^o

$$\:\:\mathrm{tan}\:\mathrm{66}°+\mathrm{tan}\:\mathrm{12}°=\sqrt{\mathrm{3}}\:+\mathrm{tan}\:\mathrm{x} \\ $$$$\Rightarrow\mathrm{2}.\mathrm{246}\:+\:\mathrm{0}.\mathrm{213}=\sqrt{\mathrm{3}\:}+\mathrm{tan}\:\mathrm{x} \\ $$$$\Rightarrow\mathrm{tan}\:\mathrm{x}\:=\mathrm{2}.\mathrm{246}+\mathrm{0}.\mathrm{213}−\sqrt{\mathrm{3}} \\ $$$$\Rightarrow\mathrm{tan}\:\mathrm{x}\:=\:\mathrm{0}.\mathrm{727} \\ $$$$\Rightarrow\mathrm{tan}\:\mathrm{x}\:=\mathrm{tan}\:\mathrm{36}^{\mathrm{o}} \\ $$$$\therefore\:\mathrm{x}=\mathrm{36}^{\mathrm{o}} \\ $$$$ \\ $$$$ \\ $$
