Here's a step-by-step solution for determining the dip and strike, and then mapping the outcrops. Part (a): Determine the dip and strike of the outcrop of the two seams. Step 1: Determine the surface elevation of each borehole from the contour map. • Borehole A is on the $800 \text{ m}$ contour line. Surface elevation at A = $800 \text{ m}$. • Borehole B is on the $700 \text{ m}$ contour line. Surface elevation at B = $700 \text{ m}$. • Borehole C is on the $600 \text{ m}$ contour line. Surface elevation at C = $600
