Answer:
What/where is the question you have for me?
Step-by-step explanation:
We know that the trigonometric identity that uses the adjacent side and the hypotenuse is cosine. We can set this up as:

We need to solve for x, so let's isolate it:

So,
x = 10.2 units
It is A because the radius is 10 which means that if x=0 then y must equal 10. (0,5) would be inside of the circle. If this doesn't make sense graph the circle and the points and you'll see what I mean.
1800 because the 18 cant fit in the tens
Answer:
A, B, E
Step-by-step explanation:
I'm not too sure about B, but A and E are definitely true
