24. Identify the center and radius of the circle given the equation (x +15)2 + (7 - 9)2 = 25 .
kykrilka [37]

Answer:

a. Center: (-15, 9), Radius: 5

Step-by-step explanation:

Equation of a circle:

The equation of a circle of center (x_0, y_0) and radius r is given by:

(x - x_0)^2 + (y - y_0)^2 = r^2

In this question, we have that:

(x + 15)^2 + (y - 9)^2 = 25

Comparing both equations:

x - x_0 = x + 15

x_0 = -15

And

y - y_0 = y - 9

y_0 = 9

The center is (-15,9).

For the radius:

r^2 = 25

r = \sqrt{25} = 5

The correct answer is given by option a.

Solve for x and y then find the measure of each angle ​
Maslowich

Step-by-step explanation:

∵ MP is a straight line.

∴ ∠MNQ + ∠PNQ = 180°

(3y + 8)° + (3y + 22)° = 180° \\ 3y + 8 + 3y + 22 = 180 \\ 6y + 30 = 180 \\ 6y = 150 \\ y = 25

∵ MP is a straight line.

∴ ∠MNR + ∠PNR = 180°

(2x + 5)° + (3x - 55)° = 180° \\ 2x + 5 + 3x - 55 = 180 \\ 5x - 50 = 180 \\ 5x = 230 \\ x = 46
