This is the correct answer to the problem
Answer: Choice A
The number line graph is visually showing every number that is 19 or smaller; hence ![x \le 19](https://tex.z-dn.net/?f=x%20%5Cle%2019)
Note the use of a closed or filled in circle at the endpoint (in contrast to an open circle). This indicates we are including the endpoint 19 as part of the solution set, and that's why we go for "or equal to" as part of the inequality sign.
Answer:no the -2/3 should be before -1/5

Answer:
![\displaystyle \sec A=\frac{65}{63}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Csec%20A%3D%5Cfrac%7B65%7D%7B63%7D)
Step-by-step explanation:
We are given that:
![\displaystyle \csc A=\frac{65}{16}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Ccsc%20A%3D%5Cfrac%7B65%7D%7B16%7D)
Where <em>A</em> is in QI.
And we want to find sec(A).
Recall that cosecant is the ratio of the hypotenuse to the opposite side. So, find the adjacent side using the Pythagorean Theorem:
![a=\sqrt{65^2-16^2}=\sqrt{3969}=63](https://tex.z-dn.net/?f=a%3D%5Csqrt%7B65%5E2-16%5E2%7D%3D%5Csqrt%7B3969%7D%3D63)
So, with respect to <em>A</em>, our adjacent side is 63, our opposite side is 16, and our hypotenuse is 65.
Since <em>A</em> is in QI, all of our trigonometric ratios will be positive.
Secant is the ratio of the hypotenuse to the adjacent. Hence:
![\displaystyle \sec A=\frac{65}{63}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Csec%20A%3D%5Cfrac%7B65%7D%7B63%7D)
