You can put this solution on YOUR website! In trigonometry, how do i know if i use
sine,
cosine,
or tangent
with a triangle?
---
Since sine = y/r you need information about 2 of those
components to find the 3rd.
---
Since cosine = x/r you need info about 2 of those
components to find the 3rd.
---
Since tangent = y/x you need info about 2 of those
components to find the 3rd.
