= 1. You are traversing along a centerline, (S 45° 00' E), at Station 1+50, you establish a BC, for a curve with R = 400', Delta 50°, which is concave to the north, and then transitions into a compound curve, also concave to the north, with R = 300', Delta = 40°, which sets an EC for this configuration. Determine the T1 and T2 from the attached Exhibit A sketch. Show your work on Exhibit A, show your answers here.
