Question

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

Explanation:

Step1: Recall the cosine formula

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

Step2: Identify adjacent and hypotenuse for angle \( P \)

For angle \( P \), the adjacent side is \( q \) and the hypotenuse is \( r \).

Step3: Calculate \( \cos P \)

\( \cos P=\frac{q}{r} \).

Answer:

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