9 is the anser trust me i just took the test i hate computer scored test but that is the answer
•cccccccccccccccccccccccccc
3 + 1 < 10
There's no question there, and nothing to solve. That's a simple statement
which, after simplifying it slightly, says " 4 < 10 ".
A statement with which, I'm sure, we can all agree.
Answer:
option C. ![-\frac{5}{13}](https://tex.z-dn.net/?f=-%5Cfrac%7B5%7D%7B13%7D)
Step-by-step explanation:
we have that
The point (-5,-12) belong to the III quadrant
so
The value of the cosine is negative
Applying the Pythagoras Theorem
Find the value of the hypotenuse
![h^{2}=5^{2}+12^{2}\\ h^{2} =25+144\\ h^{2}=169\\h=13\ units](https://tex.z-dn.net/?f=h%5E%7B2%7D%3D5%5E%7B2%7D%2B12%5E%7B2%7D%5C%5C%20h%5E%7B2%7D%20%3D25%2B144%5C%5C%20h%5E%7B2%7D%3D169%5C%5Ch%3D13%5C%20units)
The value of cosine of angle θ is the ratio between the side adjacent to angle θ and the hypotenuse
![cos(\theta)=-\frac{5}{13}](https://tex.z-dn.net/?f=cos%28%5Ctheta%29%3D-%5Cfrac%7B5%7D%7B13%7D)
<h3>Answer: Choice C</h3>
Here's how the verification would look like
![\frac{\sin^2x+\cos^2x}{\cos x} = \sec x](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csin%5E2x%2B%5Ccos%5E2x%7D%7B%5Ccos%20x%7D%20%3D%20%5Csec%20x)
using the identity here
![\sec x = \sec x](https://tex.z-dn.net/?f=%5Csec%20x%20%3D%20%20%5Csec%20x)
