Express both the bearings as if they are measured from the point where the lines intersect and then apply the above rule. To get its compass quadrant bearing requires three steps. First, decide whether the arrow is closer to N or to S. You can see it's closer to the S. Next, decide whether it's closer to the E or the W. It's closer to the E. Finally, measure the angle between the arrow and the S. That angle is 77°. GPS coordinate, also known as geodetic coordinates or “lat/long”, consists of two components. The above script carries on the loop after a match is made, so a for loop would most likely be more appropriate here: The direction of a survey line can either be established with relation to each other or with relation to any meridian. Bearing – the angle between the survey lines and the fixed line of reference with the compass True Meridian – the true or geographical meridian passing through a point is the line in which the earth’s surface is intersected by a plane through the north and south poles and the given point.
