A horizontal curve with radius equal to 220 m and intersection angle of 126° is to be realigned by rotating the forward tangent through an angle of 22° counter clockwise along the PT. If the azimuths of the back and forward tangents are 220° and 346° respectively, stationing of old PC is 10+721.20. 1. Compute the central angle of the new curve. 2. Compute the radius of the new curve. 3. What is the stationing of the new PC.
