Answer:
How to choose which trig function to use based on an angle? I'm assuming that's simpler form of the question hehe
Step-by-step explanation:
pick an angle, and look at the sides that you HAVE
if you have the side opposite to the angle, and the hypotenuse of the triangle you use sine.
if you have the side adjacent to said angle, and the hypotenuse, you use cosine.
and if you don't have the hypotenuse, but you have the other two sides, you use tangent.
