Answer:
b. ![\csc(x)](https://tex.z-dn.net/?f=%5Ccsc%28x%29)
Step-by-step explanation:
The given expression is
![\frac{\sec(x)}{\tan(x)}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csec%28x%29%7D%7B%5Ctan%28x%29%7D)
We express in terms of basic trigonometric ratios to obtain;
![\frac{\frac{1}{\cos(x)} }{\frac{\sin(x)}{\cos(x)} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B1%7D%7B%5Ccos%28x%29%7D%20%7D%7B%5Cfrac%7B%5Csin%28x%29%7D%7B%5Ccos%28x%29%7D%20%7D)
This is the same as
![\frac{1}{\cos(x)}\div \frac{\sin(x)}{\cos(x)}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Ccos%28x%29%7D%5Cdiv%20%5Cfrac%7B%5Csin%28x%29%7D%7B%5Ccos%28x%29%7D)
![\frac{1}{\cos(x)}\times \frac{\cos(x)}{\sin(x)}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Ccos%28x%29%7D%5Ctimes%20%5Cfrac%7B%5Ccos%28x%29%7D%7B%5Csin%28x%29%7D)
Cancel out the common factors;
![\frac{1}{\sin(x)}=\csc(x)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Csin%28x%29%7D%3D%5Ccsc%28x%29)
Answer:
Kenen spent $62.49
Step-by-step explanation:
