Answer: First option (incribed in the circle).
Step-by-step explanation:
As you can see in the figure shown in the problem, the triangle is inside of the circle and each vertex of that triangle touches the circle.
Then, by definition, we know that when a shape is incribed in a circle, then all the vertices of that shape must lie on the circle.
Therefore, keeping the above on mind, you can conclude the triangle is inscribed in the circle.
The answer is the first option.
Answer:

Step-by-step explanation:
The equation of the line has the following format:

In which m is the slope of the line.
We want the equation of a line:
That has slope 2, so 

Also that goes through the point (-9, 15). This means that
. So



The equation of the line is:

Answer: They read for a equal amount of time.
Step-by-step explanation:
10/12 simplifies to 5/6, making these equal.
Proof:
10 divided by 2 equals 5, and 12 divided by 2 equals 6. This means that they are equal.
