Answer:
= 9.6
Explanation:
Considering the right-angled triangle;
The radius of the circle is 16, which acts as the hypotenuse of the right-angled-triangle,
One of the shorter side is X and the other one is half of 25.6 , since a perpendicular bisector of a chord passes through the center of a circle.
Thus;
x² = 16 ² - (25.6/2)²
= 16² - 12.8²
x²= 92.16
x = sqrt 92.16
= 9.6
