So, the tangentof is. If you look in the table,you can see that an anglethat measures has a
tangentof. So,.
Example 5
Whatis in the trianglebelow?Find the tangentof and compareit to the valuesin the tableabove.So, the tangentof is about. If you look in the table,you can see that an anglethat measures
has a tangentof. So,.Noticein this examplethat is a triangle.You can use this fact to see that
.LessonSummary
In this lesson,we exploredhow to workwith differentradicalexpressionsboth in theoryand in practicalsit-
uations.Specifically, we havelearned:
- How to identifythe differentpartsof right triangles.
- How to identifyand use the tangentratio in a right triangle.
- How to identifycomplementaryanglesin right triangles.
- How to understandtangentratiosin specialright triangles.
