Types of triangles |
60:30:90 and 45:90:45 |
|
|
When there's a missing side you |
Cosø=(X/H:A:O) or Cosø=(H:A:O/X) |
|
|
When you have a missing angel you |
Tan^-1 * (O/A) =ø |
|
|
When you have two triangles with depression or elevations you |
Find the Tan:Cos:Sin of it so you get the lenght then you subtract the lenght of thr two for desired lenght |
