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

The correct answer is first option 15

Explanation:

From the figure we can see a circle with center O.

To find the value of x

Here 'x' is the radius of the given circle.

Using the given information we can write,

x² = 12² + 9²

= 144 + 81

= 225

x = √225

x = 15

Therefore the correct answer is first option 15
