Answer:
-3n-3n2+5
Step-by-step explanation:
You can use Keep Change Change in order to simplify the problem
We know that the law of sines states that:

For simplicity, let:

In triangle A1BC this leads to:

Therefore:

Now, triangle A2BC is isosceles which means that both the base angles are equal, since angle CA1B and A2A1B are supplementary we have:
This is a a reflective property because it is an if then statement.
You do not.
We have not been told if the events are mutually exclusive or not.
I hope this helps you
m=1/2
1/2 (0-x)=-2-y
-1/2x= -2-y
y=1/2x-2
