Question

what is the cosine of angle p? options: q/r, p/r, p/q, r/q

Explanation:

Step1: Recall the cosine formula

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

Step2: Identify sides for angle \( P \)

For angle \( P \), the adjacent side is \( q \) and the hypotenuse is \( r \).
So, \( \cos P=\frac{q}{r} \).

Answer:

A. \( \frac{q}{r} \)
