so I know how to find the hypotenuse but I am unable to use and find the correct formula to find the length of the other sides in the right triangle.
the formula is to be kept in the double formula2 variable

import java.util.Scanner;
public class pythagorean{
    public static void main(String[]args){
        Scanner keyboard = new Scanner(System.in);
        int option = keyboard.nextInt();
        int side1 = keyboard.nextInt();
        int side2 = keyboard.nextInt();
        double formula = Math.sqrt((side1*side1) + (side2*side2));
        double formula2 = 
        if (option == 1){
            System.out.format("%.1f",formula);
        }
        else if (option == 2){
            System.out.format("%.1f",formula2);
        } 
    }
}

What I have tried:

The code i submitted above is what i have tried so far, but i cant get the right formula

Solution 1

This is a mathematic problem rather than a coding one.
If a and b are the sides of the right triangle and c its hypothenuse, the following relations stand:

c² = a² + b² => c = sqrt(a² + b²)
a² = c² - b² => a = sqrt(c² - b²)
b² = c² - a² => b = sqrt(c² - a²)
