Two tangents that intersect at an angle of 4236 are to be connected by a compound curve consisting of a 4 curve and a 530 curve. If the tangent at the beginning of the curve to the point of intersection of the tangent is 110 m. long. 1. Compute the central angle of the first curve. 2. Compute the central angle of the second curve. 3. Compute the length of the tangent from the end of the 530 curve to the point of intersection of the tangents.
