let the slope of another line be m

Therefore, m(-2/5)= -1

=> m = 5/2

In 250-500 words explain the pythagorean theorem
Hunter-Best [27]

Answer: got u bro

The Pythagorean theorem is a formula to solve for hypotenuse the formula is a squared plus b squared equals c squared. The Pythagorean theorem was made by someone for math which is four triangles that A in the equation is for the side of the right triangle B is for the other side and C is the hypotenuse. the photographer in theorem states that the sum of the squared sides of a right triangle equals the length of the hypotenuse. It is a fundamental relationship between the three sides of a right triangle; you must use two sides in order to find the hypotenuse. many ways to make a formula for the Pythagorean theorem but the most popular one is a squared plus b squared equals c squared. there's a book and it's called the Pythagorean proposition it contains over 300 formulas for the Pythagorean theorem. a man who went by Pythagoras had found the Pythagorean theorem in the school of mathematics and Cortana he was a Greek Seaport in southern Italy he was going to get too many contributions to mathematics although some of them may have actually been the work of his students that he had taught. Pythagorean theorem is the most famous mathematical contribution in history. It was created in 1900 BC. the reason why it was created that the Egyptians wanted a perfect 90° angle to build the pyramids which were actually two right triangles whose hypotenuse form the edges of the pyramid. there is a rumor that the Chinese had also developed the Pythagoras Theorem using the areas of the sides long before Pythagoras himself.
