The value of x is 10 which is correct option (D).
What is the Angles of Intersecting Secants Theorem?
Angles of Intersecting Secants Theorem states that, If two lines intersect outside a circle, then the measure of an angle formed by the two lines is one half the positive difference of the measures of the intercepted arcs.
Given that,
Length of CW = 9 units,
Length of WV = 4 units,
Length of WU = 3 units,
Length of TW = x units,
⇒ Length of CW + Length of WV = Length of CV
⇒ 9 + 4
⇒ 13
⇒ Length of TW + Length of WU = Length of CV
⇒ x + 3 = 13
⇒ x = 10 - 3
⇒ x = 10
Hence, the value of x is 10 which is correct option (D).
