Ángulo exterior de un cuadrilátero cíclico cuando se da el ángulo interior opuesto

Dado un cuadrilátero cíclico dentro de un círculo, la tarea es encontrar el ángulo exterior del cuadrilátero cíclico cuando se da el ángulo interior opuesto.
Ejemplos: 
 

Input: 48 
Output: 48 degrees

Input: 83
Output: 83 degrees

Enfoque : 
 

• Sea, el ángulo exterior, ángulo CDE = x
• y su ángulo interior opuesto es el ángulo ABC
• como, ADE es una línea recta
• entonces, ángulo ADC = (180-x) grados
• ya que, los ángulos opuestos de un cuadrilátero cíclico son suplementarios,
• ángulo ABC = x

Below is the implementation of the above approach:
 

// C++ program to find the exterior angle
// of a cyclic quadrilateral when
// the opposite interior angle is given
 
#include <bits/stdc++.h>
using namespace std;
 
void angleextcycquad(int z)
{
    cout << "The exterior angle of the"
         << " cyclic quadrilateral is "
         << z << " degrees" << endl;
}
 
// Driver code
int main()
{
    int z = 48;
    angleextcycquad(z);
    return 0;
}

// Java program to find the exterior angle
// of a cyclic quadrilateral when
// the opposite interior angle is given
 
import java.io.*;
 
class GFG
{
 
static void angleextcycquad(int z)
{
    System.out.print( "The exterior angle of the"
        + " cyclic quadrilateral is "
        + z +" degrees");
}
 
// Driver code
public static void main (String[] args)
{
        int z = 48;
    angleextcycquad(z);
}
}

def angleextcycquad(z):
    print("The exterior angle of the",end="");
    print("cyclic quadrilateral is ",end="");
    print(z," degrees");
 
# Driver code
z = 48;
angleextcycquad(z);

using System;
 
class GFG
{
 
static void angleextcycquad(int z)
{
    Console.WriteLine( "The exterior angle of the"
        + " cyclic quadrilateral is "
        + z +" degrees");
}
 
// Driver code
public static void Main ()
{
        int z = 48;
    angleextcycquad(z);
}
}

<script>

function angleextcycquad(z)
{
    document.write( "The exterior angle of the"
        + " cyclic quadrilateral is "
        + z +" degrees");
}
 
// Driver code
var z = 48;
angleextcycquad(z);
