Given a triangle with the following parameters

$\begin{gathered} \text{opposite side=8cm} \\ \text{adkjacent side=15cm} \\ \text{hypotenuse side=17cm} \\ \text{acute angle=x}^0 \end{gathered}$

Using the trigonometry ratio formula, the cosine of an acute angle in a right angle triangle is defined as the ratio of the adjacent side to the hypotenuse.

That is;

$\cos x^0=\frac{\text{adj}}{\text{hyp}}$

Thus, the value of cos x°, is given as

$\cos x^0=(15)/(17)$

Hence, the value of cos x° is 15 ÷ 17

The correct option is the third option.
