From secant theorem, 16^2 = 8(12 + y); where y is the missing length of the secant.
256 = 8(12 + y)
12 + y = 32
y = 32 - 12 = 20

From chord theorem, 4x = 4(20)
x = 20

Step-by-step explanation:

From secant theorem, 16^2 = 8(12 + y); where y is the missing length of the secant.

256 = 8(12 + y)

12 + y = 32

y = 32 - 12 = 20


From chord theorem, 4x = 4(20)

x = 20
