Hello!
When doing Sine, Cosine and Tangent the sides of the triangle tell you what to do
The hypotenuse is H
The bottom side is A
The Straight up and down side is O
For Sine you do O / H
For Cosine you do A / H
For Tangent you do O/ A
Put in the values you Sine
Sin A = 5/ 13
Put in the values for Cosine
Cos A = 12/ 13
The answer is A) Sin A = 5/ 13, cos A = 12/ 13
Hope this helps!
