Answer:
[tex]\cos P=\dfrac{21}{29}[/tex]
B is correct
Step-by-step explanation:
In the given figure, we need to find cosine of P
In ΔPRQ, ∠R=90°. So, triangle PRQ is a right angle triangle. We can apply trigonometry identity.
As we know,
[tex]\cos\theta=\dfrac{\text{Base}}{\text{Hypotenuse}}[/tex]
In given triangle, For angle, ∠P
Base = 21
Hypotenuse = 29
Substitute into formula and we get
[tex]\cos P=\dfrac{21}{29}[/tex]
Hence, The cosine of P is [tex]\dfrac{21}{29}[/tex]
