For a bed dipping at 30 degrees, a vertical borehole 200 m along the dip direction from its outcrop meets it at a depth of about
Answer: D
Correct answer: 115 m
\[ d = 200 \times \tan 30^\circ = 200 \times 0.577 = 115.5\ \mathrm{m}. \] Confusing \( \tan \) with \( \sin \) here would give 100 m, which is the standard error: the depth below a point is a tangent relation, while the perpendicular thickness of a bed is a sine one.
