Given a triangle with the following parameters
[tex]\begin{gathered} \text{opposite side=8cm} \\ \text{adkjacent side=15cm} \\ \text{hypotenuse side=17cm} \\ \text{acute angle=x}^0 \end{gathered}[/tex]
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;
[tex]\cos x^0=\frac{\text{adj}}{\text{hyp}}[/tex]
Thus, the value of cos x°, is given as
[tex]\cos x^0=\frac{15}{17}[/tex]
Hence, the value of cos x° is 15 ÷ 17
The correct option is the third option.
