Question

The forward and back tangents of a simple curve are S 73°30’ E and N 79° E respectively. The beginning of the curve is at 10+345.43. The degree of the curve is 4.5°. For some construction reasons, it was decided to decrease the central angle by altering the direction of the forward tangent by an angle of 7°, in such a way that the end of the curve at PT and direction of the back tangent shall remain unaltered. Determine the following elements:
Radius of the old curve
Tangent of the old curve
Radius of the new curve
Tangent of the new curve
