Answer:

x = 21 units

Step-by-step explanation:

The tangent squared is equal to the secant's total length multiplied by the secant's length without the part inside the circle.

So here, that will look like: 36² = 27 * (27 + x)

Expansion and multiplication gives us: 1296 = 729 + 27x

Subtract from both sides: 567 = 27x

Divide from both sides: x = 21.

Answer:

$(x+8)^2 +(y-4)^2 = 25$

Step-by-step explanation:

Assuming this complete problem: "A cell tower is located at (-8, 4) and transmits a circular signal that covers three major cities. The three cities are located on the circle and have the following coordinates: G (-4, 7), H (-13, 4), and I (-8, -1). Find the equation of the circle"

For this case the generla equation for the circle is given by:

$(x-h)^2 +(y-k)^2 = r^2$

From the info we know that the tower is located at (-8, 4) so then h = -8 and k = 4, so then we need to find the radius. So we have the equation like this: $(x+8)^2 +(y-4)^2 = r^2$
