Question

Write a static method named anglePairs that accepts three angles (integers), measured in degrees, as parameters and returns whether or not there exists both complementary and supplementary angles amongst the three angles passed. Two angles arecomplementary if their sum is exactly 90 degrees; two angles are supplementary if their sum is exactly 180 degrees. Therefore, the method should return true if any two of the three angles add up to 90 degrees and also any two of the three angles add up to 180 degrees; otherwise the method should return false. You may assume that each angle passed is non-negative.

Explanation / Answer

//The method anglePairs checks whether or not the given three angles
   //are either complementary or supplementary angles. If so then
   //returns true otherwise returns false.
   public static boolean anglePairs(int angleA,int angleB,int angleC)
   {
       //checking for complementary angles of all possible combinatioins
       if(angleA+angleB==90 ||angleA+angleC==90 || angleB+angleC==90)
           return true;
       //checking for supplementary angles of all possible combinatioins
       else if(angleA+angleB==180 ||angleA+angleC==180 || angleB+angleC==180)
           return true;
       else
           //otherwise returns false
           return false;
   }

       else
           System.out.println("No complementary or supplementary angles are found");
      
   }

   //The method anglePairs checks whether or not the given three angles

   public static boolean anglePairs(int angleA,int angleB,int angleC)

       if(angleA+angleB==90 ||angleA+angleC==90 || angleB+angleC==90)

       else
           //otherwise returns false
           return false;
   }

}

Sample Output:

A :45
B :45
C :90
Any two angles are complementary or supplementary
A :90
B :45
C :90
Any two angles are complementary or supplementary
