Ángulo subtendido por la cuerda al centro de la circunferencia cuando se da el ángulo subtendido por la otra cuerda igual de una circunferencia congruente

Se dan dos círculos congruentes con dos cuerdas iguales. Se da el ángulo subtendido al centro de la cuerda de uno de los círculos. La tarea es encontrar el ángulo subtendido por la cuerda al centro de otro círculo.
Ejemplos: 
 

Input: z = 48
Output: 48 degrees

Input: z = 93
Output: 93 degrees

Enfoque : 
 

• En triangulo AOB y PXQ 
   

AO = PX(radii of congruent circles)
BO = QX(radii of congruent circles)
AB = PQ(equal chords)

•  
• Entonces, el triángulo AOB es congruente con el triángulo PXQ 
   
• Entonces, ángulo AOB = ángulo PXQ 
   

Cuerdas iguales de círculos congruentes subtienden ángulos iguales en sus centros.

A continuación se muestra la implementación del enfoque anterior:
