The figure is an illustration of intersecting chords.
The value of x is 16 units
How to determine the value of x?
From the figure, we can see that the two lines are intersecting chords.
To calculate the value of x, we make use of the intersecting chord theorem.
So, we have:
x * 21 = 24 * 14
Divide both sides by 7
x * 3 = 24 * 2
Divide both sides by 3
x = 8 * 2
Evaluate the products
x = 16
Hence, the value of x is 16 units
