This review exercise consists of four parts :
1- Finding the tangent ratio from given sides
2-Finding the tangent of an angle .
3- Find an angle using the Tangent ratio
4- Finding a side length using the Tangent Ratio
Now , lets start !
1-Finding the tangent ratio from given sides
Example :Find tan
0 for this triangle ,expressed as a decimal correct to four decimal places.
First , write the rule you think you are using to minimize your “goofy mistakes” as my teacher says. Then label your triangle . start with labeling the hypotenuse (its always the longest side infront of the 90 degrees angle) . After that look at were theta lies (the circle with a line in it) , the side which is opposing theta is the opposite and the last side left would be the adjacent.
see? really simple 🙂 now finally write the final statement : so tan
0 = 1.2 for this triangle
to be continued …the next question on the second topic will be on my next post
