Explanation: To solve this question let's remember the following trigonometry functions given a right triangle
[tex]\begin{gathered} sin\theta=\frac{opposite_{side}}{hypotenuse} \\ cos\theta=\frac{adjacent_{side}}{hypotenuse} \\ tan\theta=\frac{opposite_{side}}{adjacent_{side}} \end{gathered}[/tex]
Step 1: Now let's identify the sides of our triangle as follows
Step 2: Now we are able to use the trigonometry function to find con x° as follows
[tex]\begin{gathered} cosx°=\frac{adjacent_{side}}{hypotenuse} \\ cosx°=\frac{15}{17} \end{gathered}[/tex]
Final answer: So the final answer is 15 divided by 17.
