Step-by-step explanation:
In order to find the value of "x", it is important to remember that:
We can identify in the figure that:
Then:
Solving for AB:
Now, since there are 360° in a circle, we know that:
Then we can substitute into
and solve for "x". This is:
Answer:
D)
Step-by-step explanation:
Basically, if you plug in the x and y-coordinates into an equation, both sides should work out to be equal to each other:
Since , we can eliminate choice A
Since , we can eliminate choice B
Since , we can eliminate choice C
Therefore, since , then D is correct. Also,
