fill in the blank. express your answer as a simplified ratio or whole number. use the \/\ key for a ratio.
$cos(v) = square$

Explanation:

Step1: Recall cosine definition

For an acute angle in a right triangle, $\cos(\theta) = \frac{\text{adjacent side to } \theta}{\text{hypotenuse}}$

Step2: Identify sides for $\angle V$

Adjacent side to $\angle V$ is $VW = 12$, hypotenuse is $VU = 13$.

Step3: Substitute into formula

$\cos(V) = \frac{12}{13}$

Answer:

$\frac{12}{13}$
