One of the most famous formulas in mathematics is the Pythagorean Theorem. It is based on a right triangle,and states the relationship among the lengths of the sides as a^{2}+ b^{2}= c^{2}, where a and b refer to the legs of a right triangle and c refers to the hypotenuse. It has immeasurable uses in engineering, architecture, science, geometry, trigonometry, algebra, and in everyday applications. For your first post, search online for an article or video that describes how the Pythagorean Theorem can be used in the real world. Provide a one paragraph summary of the article or video in your own words. Be sure you cite the article and provide the link.

**Solution:**

For this week’s discussion I provided below a video using the Pythagorean Theorem in a real-life situation. This theorem can be used to solve many things, but in the case, in this video, it will be used to solve the length of the ladder up against a house. An example of why we would need to know the length of a ladder is that maybe we need to fix the guttering or replace a piece of siding that was damaged in a wind storm. Therefore, we would need to know the length of the ladder that is needed to reach the area on the side of the house that was damaged. We can picture the ladder leaning up against the side of the house forming a right triangle. This theorem is used to………**Please click the icon below to purchase full answer at only $5**
