Question

Please I need help it’s an emergency

Answer 1

Answer:

A. $4\sqrt{6}$

Step-by-step explanation:

Applying the leg rule which is:

$\frac{Hypotenuse}{leg} = \frac{leg}{part}$

Hypotenuse = 4 + 8 = 12

Leg = x

Part = 8

Plug in the values

$\frac{12}{x} = \frac{x}{8}$

Cross multiply

$x*x = 8*12$

$x^2 = 96$

$\sqrt{x^2} = \sqrt{96}$

$x = \sqrt{16 * 6}$

$x = 4\sqrt{6}$
