What is a fold line and how is it used? - ANSWER-The fold line is a hinge line along which a vertical cross section may be constructed and then flattened out to a horizontal or map view. It is used to represent the subsurface along any given line in a map view. It need not be perpendicular to strike. What is the angle and side relationships for the sin equation? - ANSWER-sinα = opposite side/hypotenuse What is the angle and side relationships for the tanget equation? - ANSWER-tanα = oppo...
