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

`x=25`

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`
