You are charged with determining the Point of Curve, the first non-zero deflection angle (in degrees, minutes, and seconds and in decimals), and Intersection Angle of a horizontal curve. You are given the PT, which is 84+32.4 STA, the length of the middle ordinate, which is 65.2 ft, and the radius, which is 1,521 ft. Please provide a tidy sketch of all of the values that you need to find.
