Question: A highway survey PI falls in a pond, so a cut off line AB = 275.12 ft is run between the tangents. In the triangle

A highway survey PI falls in a pond, so a cut off line AB = 275.12 ft is run between the tangents. In the triangle formed by points A, B, and PI, the angle at A = 16°28( and at B = 22°16(. The station of A is 54+92.30 ft. Calculate and tabulate curve notes to run, by deflection angles and incremental chords, a 4°30( (arc definition) circular curve at full-station increments to connect the tangents.
