If I know that sin ( θ ) = 12/13 I can use the Pythagorean theorem to find that cos ( θ ) = 5/13 . What is tan ( θ )?

1. Never mind I got the answer. Its 12/5.

sin (x) = 12/13 this is because sine is opposite divided by hypotenuse.
cos (x) = 5/13 this is because cosine is adjacent divided by hypotenuse.
tan (x) = 12/5 this is because tangent is opposite divided by adjacent.

2. Yes
You might also remember that
tan x = sin x / cos x
