2.50. There are two tangents XI and IY for a railroad circular curve where X and Y are the tangent points having coordinates (240.4E, 125.9N) and (253.8E, 218.65N), respectively, and the coordinates of the mid-point on the curve is (60.13E, 195.89N). Compute the radius of curve, the deflection angle, and the length of the curve.
