Like the title says, is it possible to position a node a certain distance away from another node at a certain angle from that node?

There are multiple ways to do this. Some of them need the calc or positioning TikZ libraries (\usetikzlibrary{calc,positioning}).
The simplest way would be (using calc TikZ-library):
\node (A) at (2,4) {<content>};
\node (B) at ($ (A) + (60:2) $) {<content>};
You can also use the coordinate options ([<options>]<coordinate>) to add a shift option, which doesn't require any libraries but looks a little funny.
\node (B) at ([shift={(60:2)}]A) {<content>};
You may want to use the trees library in tikz, which in this situation would provide, up to me, a rather easy syntax. I made a small example for you.
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning,trees,arrows}
\begin{document}
\begin{tikzpicture}[->,>=stealth',shorten <=0.5pt,
main/.style={draw,thick,rounded corners, top color=blue!20, bottom color=white,
minimum width=1cm},
child/.style={draw,thick,rounded corners, top color=red!20, bottom color=white}]
\tikzstyle{level 1}=[sibling angle=22.5]
\node[main] (a) {A} [counterclockwise from=0]
child { node[child] {1}}
child { node[child] {2}}
child { node[child] {3}}
child { node[child] {4}}
child { node[child] {5}}
child { node[child] {6}}
child { node[child] {7}}
child { node[child] {8}}
child { node[child] {9}}
;
\node[main] (ba) [below of=a] {belowA};
\path
(ba) edge (a)
;
\end{tikzpicture}
\end{document}
Which gives as result:
Best Answer
Yes, TikZ can use polar coordinates. Not sure exactly what is the best way of defining the second node, here is one way.
In
(30:2)30 is the angle, 2 the distance. 0° is to the right, positive direction is counterclockwise, so nodeBwill be above and to the right ofA.
