Answer:
19.5
Step-by-step explanation:
BY THE SECANT/TANGENT SEGMENT LENGTH THEOREM
[tex]\\x^{2}[/tex] = 10 x (28 + 10) = 10 x 38 = 3819.50
x = square root of 380 = 19.49358869 (approximately 19.5)
OPTION A
***SECANT/TANGENT SEGMENT LENGTH THEOREM
If a secant and tangent are drawn from a common exterior point, then the
product of the length of the secant with the length of its external
segment is equal to the square of the length of the tangent.
