Question

Identify the value of x.
Answers:
x = 8
x = 24
x = 7
x = 12

Answer 1

the value of x = PQ

then 'x' = 8

Answer 2

Answer:

it can be solved by a property

x=8

Step-by-step explanation:

From an external point, the products of distances to the near circle intercept and the far circle intercept are the same. For a tangent, such as PQ, point P is both the near and far intercept point, so that product is the square of the length of PQ.

(PQ)² = (QR)(QS)

x² = 4·16= 64 . . . . substitute known values

x = √64 . . . . . . . . . . take the square root

x = 8
