Question

How to find the value of x . 0 is the center of the circle . And if necessary round to the nearest tenth

Answer 1

so hmm notice the picture below

if the radius hits the chord at a right-angle, then that means, both sides of the chord are equal halves

the yellow line, is just the radius, and thus the same value as "x"

so.. .use the pythagorean theorem to get "x"
