To find the height of this tree, Sarah marked the tree at eye level, 1.8 meters above the ground. She measured 27 m from the base of the tree and then held a 5-cm ruler vertically in front of her eye until the ruler just obscured the tree above the mark. Using a string tied through a hole in one end of the ruler, Sarah found that the distance from her eye to the ruler was 5.6 centimeters. What was the height of the tree? Round to the nearest unit.


2) A church steeple casts a shadow 118 ft long, and at the same time a 7.0-ft post casts a shadow 6.0 ft long. How high is the steeple? Round to the nearest unit.

3) A lake lies between A and C, and lines AB and DE run north-south. If = 7.4 mi, = 1.6 mi, and = 1.4 mi, how far is it from A to C? Round to the nearest tenth.

the answer to 2 is 137.67. Because if 118 is proportional to 6 the same way "the height of the steeple" or "x" is proportional to 7, then if you cross multiply, then ou will get 826=6x and divide both sides by 6, you will get 137.67... Hope this helps
