\[\boxed{\mathbf{739}\mathbf{.}}\]

\[\lbrack 0;\ 3\pi\rbrack.\]

\[1)\ tg\ x = 3\]

\[x = arctg\ 3 + \pi n.\]

\[x_{1} = arctg\ 3;\]

\[x_{2} = arctg\ 3 + \pi;\]

\[x_{3} = arctg\ 3 + 2\pi.\]

\[2)\ tg\ x = - 2\]

\[x = - arctg\ 2 + \pi n.\]

\[x_{1} = - arctg\ 2 + \pi;\]

\[x_{2} = - arctg\ 2 + 2\pi;\]

\[x_{3} = - arctg\ 2 + 3\pi.\]
