The object''s shadow length and shadow

Simple geometry can compute the height of an object from the object's shadow length and shadow angle using the formula: tan(angleElevation) = treeHeight / shadowLength. Given the shadow length and angle of elevation, compute the tree height.

import java.util.Scanner;
import java.lang.Math;

public class TreeHeight {
public static void main(String [] args) {
double treeHeight = 0.0;
double shadowLength = 0.0;
double angleElevation = 0.0;

angleElevation = 0.11693706; // 0.11693706 radians = 6.7 degrees
shadowLength = 17.5;

/* Your solution goes here */

System.out.print("Tree height: ");
System.out.println(treeHeight);

return;
}
}
