On a railroad line, two tangents that intersect at station 10 + 243 so as to form an angle of 36°28′ are to be connected by a compound curve consisting of two simple curves. The simple curve beginning at the P.C. which is at station 10 + 163 is to be a 4° curve whose degree is based on a 20m chord and is to have a central angle of 17°. Using chord basis, a. What should be the radius of the other simple curve that ends at the P.T.? b. Compute the stationing of P.C.C. c. What is the length of the tangent from the P.I. to the P.T. of
