From a horizontal concordance with transition the following are known elements: stake size 20 m a) Radius of the circular curve Rc = 214.88 m; b) Deflection angle at PI = 24 12' 40" D; c) TS stake = 3 + 2.79; d) SC stake = 5 + 12.79; e) CS stake = 7 + 13.59; f) ST stake = 10 + 3.59. From these data, you are asked to determine: a) The value of the transition length (L); b) The length of the circular section (Dc); c) The value of the angle that subtends the transition stretch (Os), in radians and in degree, minute and second; d) The coordinates (Xs; Ys) of the SC point, considering only the first three terms of the equations for Xs and for Ys; e) The coordinate values (q; p) of the offset from the circular curve
