Question

find: \\( \cos a \\)
answer

Explanation:

Step1: Recall the cosine formula

In a right - triangle, $\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}$. For angle $A$, the adjacent side to angle $A$ is $65$ and the hypotenuse is $97$.

Step2: Calculate $\cos A$

Using the formula $\cos A=\frac{65}{97}$.

Answer:

$\frac{65}{97}$
