The answer is D i just did this question myself lol

Step-by-step explanation:

The diameter of the circle is the distance from the endpoint to another endpoint. The diameter of the given circle is segment PQ. To determine the diameter of the circle, we would apply the formula for determining the distance between two points on a straight line is expressed as

Distance = √(x2 - x1)² + (y2 - y1)²

Therefore,

Diameter = √(1 - - 3)² + (9 - 5)²

Diameter = √4² + 4² = √32

Radius = diameter/2 = √32/2

A circle is the set of all points in a plane equidistant from a fixed point called the origin or center.

The center of the circle is determined by applying the midpoint formula

(x1 + x2)/2, (y1 + y2)/2

= (- 3 + 1)/2, (5 + 9)/2

Center = (- 1, 7)

The formula for determining the equation of a circle us expressed as

(x - h)² + (y - k)² = r²

Where

r represents the radius of the circle

h and k represents the x and y coordinates of the center of the circle. Comparing with the given points,

h = - 1 and k = 7

Substituting into the formula, it becomes

(x - h)² + (y - k)² = r²

(x - - 1)² + (y - 7)² = (√32/2)²

(x + 1)² + (y - 7)² = 32/4

(x + 1)² + (y - 7)² = 8

What question? I don’t understand?

The main thing is when we have a transversal across parallel lines we generate a bunch of angles, which they've numbered 1 through 8. Some are the same angles, some are supplementary angles, which means they add up to 180°. So really for math you just need to know whether it's the same or the supplement, which is pretty obvious from the figure.

But here they want us to match the names. I can never remember them but we're given a menu.

∠2 and ∠5 are alternate interior angles. Alternate means on opposite sides of the traversal. Interior means between the parallel lines. Say the mantra: Alternate interior angles are congruent.

∠3 and ∠5 are none of the above. They're supplements but I don't think they have a name. Usually we proceed in two steps. ∠3 and ∠1 are a linear pair so supplementary. ∠1 and ∠5 are corresponding angles so are congruent.

∠3 and ∠8 are alternate exterior angles. Exterior means outside the parallel lines. Alternate exterior angles are congruent.

∠4 and ∠7 are alternate interior angles so congruent.

∠4 and ∠8 are corresponding angles so congruent.

They didn't give an example, but ∠3 and ∠4 are vertical angles, and vertical angles are congruent.
