Now find the geometricmeanof and to identifythe lengthof the altitude.

So, inches.

LessonSummary


In this lesson,we exploredhow to workwith differentradicalsboth in theoryand in practicalsituations.
Specifically, we havelearned:



  • How to identifysimilartrianglesinscribedin a largertriangle.

  • How to evaluatethe geometricmeanof variousobjects.

  • How to identifythe lengthof an altitudeusingthe geometricmeanof a separatedhypotenuse.

  • How to identifythe lengthof a leg usingthe geometricmeanof a separatedhypotenuse.
