Answer:

Step-by-step explanation:

Let X be the midpoint of the chord AB

Distance between X and the centre:

15-3 = 12

XB² = 15² - 12²

XB² = 81

XB = 9

AB = 2XB = 18

ΔABC is a right triangle in which is a right angle, AB = 1, AC = 2, and BC = .

ollegr [7]

We are asked to solve for the measurement of side BC in the given right triangle ΔABC and other side measurements were also given such as AB=1 and AC = 2. Since this is a right triangle, we can use and apply the Pythagorean theorem c²= a² + b² and the solution is shown below:
c = AC
b = BC
a = AB
AC² = AB² + BC² , substitute values we have:
2² = 1² + BC²
BC² = 4-1
BC = √3
BC = 1.732

The answer for the length of BC is 1.732 units.
