C= 2R*sin{(1/2)*I}.
Where C= length of long chord.
c=30 , R=300.
=>(30/600)= sin{(1/2)*I}.
=>(1/20) = sin{(1/2)*I}.
=>I = 2*{sin^-1(1/20)}.
=>I = 5.73 Degree.

R = 1718.9/D.
R: Radius of curve.
D: Degree of curve.
D = 1718.9/R.
D = 5.73°.
R: Radius of curve.
D: Degree of curve.
D = 1718.9/R.
D = 5.73°.

@All.
Someone are directly using 1719 or 1718 but this will only work if length of chord is 30 m so use basic formula c = r sin (d/2).

R=1719/D or; D=1719/R,or D=1719/300=5.73°.
