Question

12/20 which triangle below shows the ratio as \\( \cos ( x ) = \frac { u } { v } \\)?

Explanation:

Step1: Recall the cosine formula

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

Step2: Analyze the second triangle

For the second triangle, the angle \(x\) has adjacent side \(u\) and hypotenuse \(v\). Using the formula \(\cos(x)=\frac{\text{adjacent}}{\text{hypotenuse}}\), we get \(\cos(x)=\frac{u}{v}\).

Answer:

The second triangle.
