Answer:
Your answers are correct.
Step-by-step explanation:
Sine = Opposite Side/Hypotenuse
Cosine = Adjacent Side/Hypotenuse
Tangent = Opposite Side/Adjacent Side
(This general rule is commonly referred to as SOHCAHTOA.)
In your case, the opposite side is 5, the adjacent side is 12, and the hypotenuse is 13.
Sin(theta) = 5/13.
Cos(theta) = 12/13.
Tan(theta) = 5/12.
You're good to go!
