How to calculate an angle of a right triangle given opposite and hypotenuse in Java

Answer 1

public class MyClass {
    public static void main(String args[]) {
        float opposite = 2.5f;
        float hypotenuse = 5f;
  
        double angle_sin = opposite / hypotenuse;
        double right_triangle_angle = Math.asin(angle_sin) * 180 / Math.PI;
  
        System.out.println("Right Triangle Angle = " + right_triangle_angle);
    }
}


 
  
  
  
  
/*
run:
  
Right Triangle Angle = 30.000000000000004
  
*/
