(-1, 5)
<u>Step-by-step explanation:</u>
The center of a circle is the midpoint of the diameter.
So we have to calculate the midpoint of the diameter, using this formula:
midpoint = (
,
)
= (
,
)
= (-1, 5)
∴ The center of the circle lies at the point (-1, 5).
Answer: x = 11
To start, we know that a whole circle equals 360 degrees. If we subtract the 2 arcs we know, 85 and 31, we have 244 degrees left for the 2 congruent arcs. Dividing that by 2 gives us 122 for each arc.
Now, write the equation: 122 = 13x - 21
Solve this, to find the x = 11.
