Question

What is the value of x to the nearest tenth?

4.7

8.0

3.3

9.5

Answer 1

We know that the line segment drawn from the center of circle to any chord , bisects the chord

So the other part fo the chord is also 6.5

And the radius is 8

, So we can now apply the pythagorean theorem , in the triangle

So

$x^{2}+6.5^{2} = 8^2$

$x^2 = 64 - 42.25$

$x^2 = 21.75$

taking square root on both sides

x = 4.6637

x=4.7

Answer 2

The answer is 4.7. Good luck with the rest
