Question

Suppose Ø is an angle in standard position with cos Ø>0. In which quadrant(s) could the terminal side of Ø lie? Select all that apply.

Answer 1

I think the answer is
I and IV quadrant

Answer 2

Answer:

I and IV quadrant

Step-by-step explanation:

we know that

In the I quadrant

the value of $cos(\phi)$ is positive

the value of $sin(\phi)$ is positive

In the II quadrant

the value of $cos(\phi)$ is negative

the value of $sin(\phi)$ is positive

In the III quadrant

the value of $cos(\phi)$ is negative

the value of $sin(\phi)$ is negative

In the IV quadrant

the value of $cos(\phi)$ is positive

the value of $sin(\phi)$ is negative

therefore

the answer is

I and IV quadrant
