height of a building
firemen , construction workers and other workers often rely on the use of ladders in their line of work . for ex the height to a second story window may be 25 feet and a window cleaner may need to put the ladder ten feet away from the building in order to avoid bushes. so for this task the window cleaner will need a ladder this feet long -
25^2 + 10^2 = C^2
625 + 100 = 725
square root of 725 is 27
so the window cleaner would need a ladder 27 feet long.
In real life its not useful, unless you're going to need geometry in the career you choose.
You work as a house painter. When you set up your ladder, you like to set the base 5-ft from the wall, for stability. How high on the wall can you reach with a 12-ft ladder ? With a 15-ft ladder ? With a 30-ft ladder ? ============================================================== The question is not: Can the Pythagorean Theorem help you in real life ? The question is: Is your life real enough yet that you can use the Pythagorean Theorem to make it easier ?
