Answers: cos A=b/a, sin J=j/l, tan K=k/j
Explanation: The trig ratios are SohCahToa or Sin(o/h), Cos(a/h), and Tan(o/a).
When A is the reference angle, b is the adjacent side and a is always the hypotenuse (Cah).
When J is the reference angle, j is the opposite side and l is always the hypotenuse (Soh).
When K is the reference angle, k is the opposite side and j is the adjacent side (Toa).
