Answer 35

Strike/dip

Question 36

3 point problem steps (4)

Answer 36

1. Connect high and low points
2. Scale and locate a point on this line at the same elevation of the intermediate point. Connect these points. This is the strike line.
3. To find the dip, draw a perpendicular line from the strike line to a high/low point.
   dip = arctan((h(high/low) - h(strike)) / d(high/low strike))
4. Use the RHR to find the strike.
