MEDAL!!!!

OpenStudy (jessiegonzales):

10. (TRIANGLE) ABC has side lengths 18,24 and 30. Do the side lengths form a Pythagorean triple? A. yes B no

OpenStudy (danjs):

a pythagorean triple... do the sides satisfy c^2 = a^2 + b^2

OpenStudy (jessiegonzales):

no

OpenStudy (danjs):

30^2 = 24^2 + 18^2 ???

OpenStudy (danjs):

then not a pythagorean triple

OpenStudy (jessiegonzales):

thanks

OpenStudy (danjs):

but they actually do satisfy that

OpenStudy (jessiegonzales):

they do?

OpenStudy (danjs):

30^2 = 900 and 24^2 + 18^2 = 900

OpenStudy (jessiegonzales):

576+324 10,728

OpenStudy (danjs):

A triangle with side lengths 30,24,18 form a RIGHT triangle

OpenStudy (jessiegonzales):

10,728=900

sammixboo (sammixboo):

Hmm, where did you get 10,728 from?

OpenStudy (danjs):

24^2 = 576 18^2 = 324 ------------- 24^2+18^2 = 900

OpenStudy (jessiegonzales):

ooops i mean 900

OpenStudy (jessiegonzales):

900=900

OpenStudy (jessiegonzales):

yes is the answer

OpenStudy (danjs):

right, to check in the future, take the longest side as C, and find if C^2 = A^2 + B^2

OpenStudy (jessiegonzales):

thanks
