While drawing a $30^\circ$ angle for a problem, the figure should approximately satisfy—

For an elevation angle below $45^\circ$, the opposite (perpendicular) side is shorter than the adjacent (base) side, since $\tan 30^\circ = \frac{1}{\sqrt{3}} < 1$ means perpendicular/base $< 1$. So the base must be drawn longer than the perpendicular.
