The theorem state that the products of the lengths of the line segments on each chord are equal. The value of x from the figure is 15.75
The theorem state that the products of the lengths of the line segments on each chord are equal.
According to the given diagram;
9 * 21 = 12 * x
189 = 12x
Divide both sides by 12
12x/12 .= 189/12
x = 189/12
x = 15.75
Hence the value of x from the figure is 15.75
