What is the value of x in the diagram below?

VARVARA [1.3K]

Answer:

option B is the right option.

Step-by-step explanation:

<h3>Using leg rule</h3>

$\frac{bc}{ab} = \frac{ab}{bd}$

Plug the values:

$\frac{20}{12} = \frac{12}{x}$

Apply cross product property

$20 \times x = 12 \times 12$

Calculate the product

$20x = 144$

divide both sides of the equation by 20

$\frac{20x}{20} = \frac{144}{20}$

Calculate:

$x = 7.2$

hope this helps..

Good luck...
