Answer:
22-10c
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
4w+5 just add that and you find your anser
Both the work and explanation is in the picture.
