find the value of the trigonometric ratio in reduced form.
cos a
cos a=

Explanation:

Step1: Recall cosine ratio formula

In a right - triangle, $\cos A=\frac{\text{adjacent}}{\text{hypotenuse}}$.

Step2: Identify adjacent side and hypotenuse

For angle $A$, the adjacent side to angle $A$ is $AB = 30$, and the hypotenuse is $AC=34$.

Step3: Calculate the cosine value

$\cos A=\frac{30}{34}$.

Step4: Simplify the fraction

$\frac{30}{34}=\frac{30\div2}{34\div2}=\frac{15}{17}$.

Answer:

$\frac{15}{17}$
