We have:

Then we use trigonometric identities to change the negative sign of the trigonometric functions, so:

We clear f(x):

we simply what we can:

Thus, the correct answer is;
Answer:
Slope is m= -1
Step-by-step explanation:
Use the slope formula to find the slope m
.
y=mx+b
It is impossible to determine the relationship between x and y from the question about the triangle. Hence, the correct option is D. This is because none of the sides are labelled x or y from the information provided.
<h3>What are the relationships that exist between the sides of a triangle?</h3>
It is important to note that:
The side with the highest length is the side that is opposite the biggest angle.
It is also important to note that the angle that is least will always be opposite the side that is smallest.
