what-is-the-perimeter-of-a-right-triangle-with-a-leg-of-10-units-and-a-hypotenus
The perimeter is ##10+3sqrt{3}+sqrt{127}## units.
The hypoteneuse squared is 127. One leg squared is 100. The other leg squared must be the difference, ##127-100=27##. Thus the length of that leg is ##sqrt{27}=3sqrt{3}##.
