Question 663980
<font face="Times New Roman" size="+2">


6 ft.  The line from the top of Hal's head to a point Hal's height above the ground on the tree, the line from that point to the top of the tree, and the line from the top of the tree to Hal's head form a right triangle.  The measure of one leg is 40 feet and the measure of the hypotenuse is 50 feet, so the measure of the other leg must be 30 feet (3-4-5 right triangle).  The part of the tree from Hal's height up then measures 30 feet, but the tree is 36 feet tall, so Hal must be 36 minus 30 equals 6 feet tall.
