ABC Pascal: The value of the angle α is given in radians (0 ≤ α 2 · π). Determine the value of the same angle in degrees, taking into account that 180 ° = π radians. Use 3.14 for π.

If 180 ° is equal to π radians, then 1 radian = (180 ° / π) degrees.

For a radians the formula will be valid:

and radians = ((a * 180 °) / π) degrees.

The last formula is used in the program.

program rad_to_gr;

var a: real;

begin

writeln (‘Enter the angle value in radians’);

readln (a);

a: = (a * 180) /3.14;

writeln (‘Angle value in degrees:’, a: 0: 2)

end.
