Answer: Draw a perpendicular on the given chord from the center of the circle we know it divides the chord in to equal parts Join the centre of circle and end point of the chord you will get right angled triangle let the distance be x using Pythagorean theorem 8²=6²+x² 64=36+x² x²=28 x=√28 x=2√7 Reply
Answer:
Draw a perpendicular on the given chord from the center of the circle
we know it divides the chord in to equal parts
Join the centre of circle and end point of the chord
you will get right angled triangle
let the distance be x
using Pythagorean theorem
8²=6²+x²
64=36+x²
x²=28
x=√28
x=2√7
