Answer:

y = 11.2 in

Step-by-step explanation:

Given a tangent and a secant from an external point to a circle, then

The square of the measure of the tangent is equal to the product of the external part and the entire secant, that is

5(5 + y) = 9²

25 + 5y = 81 ( subtract 25 from both sides )

5y = 56 ( divide both sides by 5 )

y = 11.2

Hope it helps! ^w^

Find the root(s) of the equation x2 = 169? A) x = ±13 B) x = ± 13 C) x = 13 D) x = 13

ss7ja [257]

Answer:

We have this equation:

$x^2 = 169$

What we do is a square root on both sides, so we get:

$\sqrt{x^2}=\sqrt{169}$

$x = \sqrt{169}$

And now, we calculate the square root, remember tehre are always two results when the root index is even:

$\bold{x_1 = 13}$

$\bold{x_2 = -13}$

As 13 * 13 = (-13)*(-13)
