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. 1. Using simple algebra, rearrange that equation to solve for treeHeight. 2. Write a statement to assign treeHeight with the height calculated from an expression using angleElevation and shadowLength.

code:

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; } }
