Question

Find the value of x. If necessary, round your answer to the nearest tenth. O is the center of the circle. The figure is not drawn to scale.

Answer 1

Answer:

$x=25$

Step-by-step explanation:

we know that

In this problem

The value of x represent the radius of the circle

so

Applying the Pythagoras theorem in the right triangle of the figure, you can find the radius of the circle O

see the attached figure to better understand the problem

$x^{2} =20^{2}+15^{2}$

$x^{2} =400+225$

$x^{2} =625$

square root both sides

$x=25$
