And 20-21-29 is a different triple.<br /><br />That said, the answer is still "obviously" 21 because it is the hypotenuse, so 19 and 20 are out, and 20-7-27 is not a valid triangle, let alone a right triangle. <br /><br />Answer modified above.(x, why?)https://www.blogger.com/profile/17499160002806879025noreply@blogger.comtag:blogger.com,1999:blog-28172905.post-17517248354417701532015-10-01T16:26:08.362-04:002015-10-01T16:26:08.362-04:007-20-21 is not a triple.

Your explanations for arriving at the answers to Part I questions were very helpful to me and will make it much easier for me to show my student how to write out the work.
