Knowledge of special triangles is needed to solve this by hand.

π3 is 1803=60

One of the special right triangles is 306090 where the sides have lengths with the following ratios.

30x
60x3
902x

If we let x=1 then the side lengths are 1,3,and2 respectively.

tan(θ)=oppositeadjacent=yx

tan(π3)=31=3
