Find the cosine of angle p. a.20/29 b.21/29 c.20/21 d.21/20

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,

In given triangle, For angle, ∠P

Base = 21

Hypotenuse = 29

Substitute into formula and we get

Hence, The cosine of P is
