The correct answer is D. x = 11.1

Step-by-step explanation:

The two chords in the circle are intersecting with each other and are divided into two sub parts.

By Chord intersection theorem we have : If the two chords intersect with each other then the product of their corresponding sub parts is equal.

So, to find x :

⇒ 26 × 6 = x × 14

⇒ 14·x = 156

⇒ x = 11.1 units

Therefore, The correct answer is D. x = 11.1
