there are two chords AB and CD in a circle AB =10 CD=8 and the radius of the circle is 12.what is the distance of each Chord from the center of the circle

I need the answer please

This is "government"?

Anyway:
draw one of those cords in the circle, say AB = 10.
now draw lines from the center of the circle to each end of the chord.
The length of those chords is the circle radius, 12 inches or meters or whatever.
Now draw an altitude from the center to the center of the chord.
Now you have two right triangles with hypotenuse 12 and leg 5
The other leg is your answer
x^2 = 12^2 - 5^2 = 144 - 25 = 119
so answer = 10.90871211
