4. Suppose that a compound curve deflection angle is 152º and the tangent length of the compound curve is 390 m (tu) and first simple curve radius (R.) is 250 m and its deflection angle (A2) is 78° a) Draw the compound curve and show the elements on it (10p) b) Calculate the second simple curve radius (15p) c) Check whether R/R2 or R/R, is right or not. (5p)
