8 0

Answer:

center: (-1 , 5)

radius: 7

Step-by-step explanation:

circle: (x – h)²+ (y – k)² = r², with the center at (h, k) and the radius "r"

x² + y² + 2x - 10y - 23​ = (x + 1)² + (y - 5)² - 49 = 0

(x + 1)² + (y - 5)² = 49 = 7²

center: (h , k)   (-1 , 5)

radius: 7

Triangle X Y Z is shown. Angle X Z Y is 90 degrees and angle X Y Z is 41 degrees. The length of Z X is 22.
skad [1K]

The equation that could be used to solve for the length of XY is XY = 22/sin(41)

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Sine rule is used to show the relationship between the sides and angles of a trinagles.

Using sine rule on triangle XYZ:

XY / sin(Z) = XZ / sin(Y)

XY / sin(90) = 22/sin(41)

XY = 22/sin(41)

The equation that could be used to solve for the length of XY is XY = 22/sin(41)
