We can find any unknown angle from a right-angled triangle, as long as we know the lengths of two of its sides.
all we need is to use Sine, Cosine or Tangent
But Which One?
It depends which two sides you know:
-Adjacent is adjacent to the angle,
-Opposite is opposite the angle,
-and the longest side is the Hypotenuse
Then use the phrase "sohcahtoa" to decide which one of Sine, Cosine or Tangent to use:
...
Sine = Opposite / Hypotenuse
......
Cosine = Adjacent / Hypotenuse
...
Tangent = Opposite / Adjacent
for example, we know the length of:
1. the side called the “Opposite”, and
2. the “hypotenuse”
And in “sohcahtoa” that is “o” (from Opposite) and “h” (from hypotenuse), and that gives us
“SOHcahtoa” ... which tells us to use
