Question
ANSWER THE SECOND PICTURE ONLY. SURVEYING. ROUND OFF THE ANSWER TO TWO DECIMAL PLACES.
A simple curve connects two tangents XY and YZ.
The survey data are the following:
Bearing of XY = N 85° 30' E
Bearing of YZ =S 68° 30' E
Station of Vertex / Intersection = 4 + 360.2
Station of Point of Curvature = 4 + 288.4
