The equation of a circle is (x - h)² + (y - k)² = radius²
where the center is represented by (h, k).
So to plug in:
(x - (-2))² + (y - 1)² = radius²
(x + 2)² + (y - 1)² = radius²
To find the radius, you can do the distance formula OR (and I suggest this one) use common sense. The center and point given have the same Y-value meaning they are in a horizontal line. Because of this, you can just find the distance between them (AKA your radius) by doing the absolute value of their difference:
|- 4 - (-2)| = |- 4 + 2| = |-2| = 2
Just to show order doesn't matter:
|- 2 - (-4)| = |- 2 + 4| = |2| = 2
Your radius is 2. Plug this into your equation and simplify.
(x + 2)² + (y - 1)² = (2)²
Your answer is:
(x + 2)² + (y - 1)² = 4

Angles 5 and 7 are vertically opposite angles.
angle 5=angle 7
angles 4 and angle 4 are co interior and are supplementary angles
implies that angles 4 and 7 sum up to 180 degrees
angle 4 = 180 -114 =66 degrees
Answer:
x=1/2
Step-by-step explanation:
10-2x=14x+2
8/16=16x/16
x=1/2
