Question

find: \\( \cos b \\)
the figure is not drawn to scale

Explanation:

Step1: Recall cosine formula

In a right - triangle, \(\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}\)

Step2: Identify sides for angle \(B\)

For angle \(B\), adjacent side \( = 7\), hypotenuse \(=25\)

Step3: Calculate \(\cos B\)

\(\cos B=\frac{7}{25}\)

Answer:

\(\frac{7}{25}\)
