A tree casts a shadow 36 ft long. At the same time, the shadow cast by a vertical 5 - ft pole is 4 ft long. Find the height of the tree The tree's height is 37.5 ft .

Did you know that the relationship between the height of an object and its shadow can be explained using similar triangles? When two objects cast shadows under the same light source, the ratios of their heights to their shadow lengths are equal. In your example, the pole's height to its shadow length can be compared directly to the tree's height to its shadow length, leading to the formula: (height of pole/length of pole's shadow) = (height of tree/length of tree's shadow). To avoid common mistakes, double-check your unit conversions and ensure all measurements are consistent. It’s easy to get tangled up in numbers! When setting up your proportions, make sure you're following the ratios correctly and watch out for simple arithmetic errors. A small mistake in calculations can lead you to a wildly inaccurate height for that majestic tree!
