You can identify that the triangle given in the exercise is a Right triangle. Then, you can use these Trigonometric identities:


\sin x\degree=(opposite)/(hypotenuse)
\cos y\degree=(opposite)/(hypotenuse)

You have to find the hypotenuse of this triangle. You can find it using the Pythagorean theorem:


a^2=b^2+c^2

Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.

You can set up that:


\begin{gathered} b=12 \\ c=5 \end{gathered}

Substituting values and solving for "a", you get:


\begin{gathered} a^2=12^2+5^2 \\ a=\sqrt[]{169} \\ a=13 \end{gathered}

Then:


hypotenuse=13

Substituting values, you get:


\sin x\degree=(5)/(13)
\cos yº=(5)/(13)

You can notice that the ratios are identical.

The answer is:


\sin x\degree=(5)/(13)
\cos yº=(5)/(13)

The ratios are identical.
