1. **State the problem:** Given two tangents intersecting at station 4107, with angles $I_1=31^\circ$, $I_2=35^\circ$, deflection angles $D_1=3^\circ$, and $D_2=5^\circ$, find the

1. **Problem restatement:** We have two converging tangents intersecting at an angle of 30°. The second curve's degree is 6°, its distance from Point of Intersection (PI) to this i
