Answer 1

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!
