Answer:
![\sec y=\dfrac{q}{r}](https://tex.z-dn.net/?f=%5Csec%20y%3D%5Cdfrac%7Bq%7D%7Br%7D)
Step-by-step explanation:
Given that,
![\sin y=\dfrac{7}{q}](https://tex.z-dn.net/?f=%5Csin%20y%3D%5Cdfrac%7B7%7D%7Bq%7D)
and
![\tan y=\dfrac{7}{r}](https://tex.z-dn.net/?f=%5Ctan%20y%3D%5Cdfrac%7B7%7D%7Br%7D)
We need to find the value of
. We know that,
![\sec\theta=\dfrac{1}{\cos\theta}](https://tex.z-dn.net/?f=%5Csec%5Ctheta%3D%5Cdfrac%7B1%7D%7B%5Ccos%5Ctheta%7D)
Also,
![\tan\theta=\dfrac{\sin\theta}{\cos\theta}\\\\\cos\theta=\dfrac{\sin\theta}{\tan\theta}](https://tex.z-dn.net/?f=%5Ctan%5Ctheta%3D%5Cdfrac%7B%5Csin%5Ctheta%7D%7B%5Ccos%5Ctheta%7D%5C%5C%5C%5C%5Ccos%5Ctheta%3D%5Cdfrac%7B%5Csin%5Ctheta%7D%7B%5Ctan%5Ctheta%7D)
Substitute all the values,
![\cos y=\dfrac{\dfrac{7}{q}}{\dfrac{7}{r}}\\\\=\dfrac{7}{q}\times \dfrac{r}{7}\\\\\cos y=\dfrac{r}{q}](https://tex.z-dn.net/?f=%5Ccos%20y%3D%5Cdfrac%7B%5Cdfrac%7B7%7D%7Bq%7D%7D%7B%5Cdfrac%7B7%7D%7Br%7D%7D%5C%5C%5C%5C%3D%5Cdfrac%7B7%7D%7Bq%7D%5Ctimes%20%5Cdfrac%7Br%7D%7B7%7D%5C%5C%5C%5C%5Ccos%20y%3D%5Cdfrac%7Br%7D%7Bq%7D)
So,
![\sec y=\dfrac{1}{\dfrac{r}{q}}\\\\\sec y=\dfrac{q}{r}](https://tex.z-dn.net/?f=%5Csec%20y%3D%5Cdfrac%7B1%7D%7B%5Cdfrac%7Br%7D%7Bq%7D%7D%5C%5C%5C%5C%5Csec%20y%3D%5Cdfrac%7Bq%7D%7Br%7D)
So, the correct option is (a) i.e.
.
Answer:
there aren't any options. but quadrant four would have a (x,-y) set up. positive x-values, but negative y-values.
