CODE:

import java.util.*;
public class TreeHeight {
public static void main(String args[]) {
Scanner scnr=new Scanner(System.in);
double treeHeight;
double shadowLength;
double angleElevation;
angleElevation =scnr.nextDouble();
shadowLength =scnr.nextDouble();

treeHeight=(Math.tan(angleElevation))*shadowLength;

System.out.println(treeHeight);

  
}
}

OUTPUT:

0.11693706 17.5 2.055777526488276
