Chris wants to measure the height of a tree. He’s sites the top of the tree using the mirror that is lying flat on the ground. The mirror is 37 feet from the tree and Chris is standing 12.3 feet from the mirror. His eyes are 6 feet above the ground. How tall is the tree? Round your answer to the nearest foot.

Amountain climber starts a climb at an elevation of 453 feet above sea level at his first rest stop he has climbed 162 feet and by his second rest stop he has climbed another 207 feet its getting late in the day so the climber starts his way down if the climber desends 285 feet how much does he need to ascend or descend to return to the original starting point
