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

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

i believe the answer is the polygon, heptagon.
